Which Planet Pairs Does the Synastry Comparison Report Compare?

What does the live report document as input and output?

The Synastry Comparison Report documents six sign inputs: each person supplies Moon, Venus and Mars. Degrees are optional, and its instructions say to leave a placement unknown when you are unsure. The page also describes input-by-input sign comparison and, when both degrees are supplied, a shortest-angle calculation checking five major aspects within a fixed 6° orb. These are the public details established by “Synastry Comparison Report.”

Here, a cross-chart pair means one placement belonging to one person’s chart considered with a placement belonging to the other person’s chart. The product page does not enumerate which directional pairs appear in the completed report. The six inputs make a full pairing map conceivable, but that implication does not verify the report’s displayed outputs. A 3-by-3 map can still help organize the possible combinations; it should be read as an editorial guide derived from the inputs, not a product feature the page confirms. That boundary keeps the answer tied to what readers can inspect publicly.

Can the six inputs be organized into a 3-by-3 map?

Yes, as a way to organize every possible cross-chart combination. Put one person’s three placements down the rows and the other person’s three across the columns: Moon, Venus and Mars on each side. Each row can meet each column, so the map has 3 × 3, or nine, possible cells. That count follows from the six input categories listed in “Synastry Comparison Report”; it is a transparent combinatorial derivation, not a count reported by the product.

The labels belong to chart owners, not to a generic pair of planets. If the rows represent Person A and the columns Person B, the Moon row and Venus column mean A’s Moon with B’s Venus. The reverse cell, A’s Venus with B’s Moon, asks about a different placement in each chart. Both use the same two planet names, yet the ownership has changed. Keeping the order visible prevents a reader from treating the pair as interchangeable when interpreting whose placement is being considered.

A compact reader’s map would therefore label its cells as “possible cross-chart combinations derived from the input set.” Its rows and columns might be shown like this in prose: A’s Moon can be paired with B’s Moon, Venus or Mars; A’s Venus can be paired with B’s Moon, Venus or Mars; and A’s Mars can be paired with B’s Moon, Venus or Mars. This spells out the nine combinations without inventing signs, degrees or a couple’s chart. It is a way to see the full set that could be formed from the supplied categories. The labels describe possible comparisons only; they do not assert that a calculation or interpretation exists for a particular cell.

The distinction matters when moving from a list of inputs to a claim about a report. “Input-by-input comparison,” the product page’s wording, reasonably suggests that submitted placements are compared. But the page does not name each ordered pairing or say that nine separate cells appear in the output. A reader may expect exhaustive pairing; expectation is not confirmation. To say that the report actually displays every cell would require evidence from a verified report or an explicit product description, which the cited page does not provide. Nor does “input-by-input” specify whether the interface groups results by person, planet, aspect, or another presentation choice.

So use the grid to frame a question about coverage, not to predict what the interface returns. It can help someone check which two chart-owned placements they mean when they ask about a cross-chart comparison. The exact output mapping remains an open product detail until it is documented. This keeps the map useful while preserving a clear line between arithmetic and confirmed product behavior.

Why is a possible pair different from an aspect?

A possible pair names two placements from different charts; an aspect describes the angular relationship between their positions. Those are related questions, but they are not interchangeable. “Getting the Most from Your Professional Natal Report” uses aspect for a relationship defined by angular distance. The product page, “Synastry Comparison Report,” separately describes sign comparison and a shortest-angle calculation when degrees for both positions are supplied. So a Moon–Venus pairing can be identified as a comparison even before anyone can say whether those two placements form one of the report’s angular contacts.

The calculation has a clear order. First identify which two chart-owned placements are being considered. Then use each placement’s zodiac position, calculate the shorter separation around the zodiac circle, and compare that separation with a target angle under the report’s stated rule. “Synastry Comparison Report” says the angle check uses five major aspects and a fixed 6° orb when both degrees are available. That is the product’s disclosed test; it does not follow just from writing two planet names beside one another. The calculation asks whether their positions meet a geometric condition, not merely whether the pair exists in the comparison set.

This distinction also clarifies what a sign-level comparison can say. Two supplied sign names still let a reader consider the placements together at the symbolic sign layer. But without the positions needed for the angle step, the pair cannot be called a confirmed angular contact under the product’s degree-based method. A sign pattern may look suggestive in a broad sign-based reading, and that can be a meaningful symbolic observation. It does not reveal the exact separation of the two placements. Keeping the layers distinct lets the pair remain useful without making the geometry say more than the available information supports. In other words, a sign-based resemblance between two placements and an aspect label answer different kinds of questions: one compares symbolic categories, while the other classifies measured positions. Neither label needs to erase the other, but only the latter depends on angular geometry.

A practical reading sequence is therefore: name the two placements and their chart owners; compare their signs for the sign-level question; then, only where both positions are known, assess the angular relationship by the stated calculation. The first step defines the pair. The later step tests a different property of it. This prevents a list of possible pairs from being mistaken for a list of aspects, and it prevents a symbolic sign comparison from silently turning into a degree result.

Why do signs alone leave the angle question open?

A sign name identifies a 30-degree sector of the zodiac, while a degree locates a position within that sector. “Synastry Comparison Report” makes use of both kinds of information for different purposes: it offers sign-level comparison, and it describes a shortest-angle check only when both placement degrees are supplied. The sign labels tell you which sectors contain the placements. On their own, they do not tell you where inside those sectors the placements fall, so they cannot establish the precise distance between them.

Imagine two marks placed somewhere inside one labeled sector. The labels match, but the marks could sit close together or farther apart. The same is true of two placements with the same sign: the shared sign does not fix their separation. If two placements occupy different signs, the sign names still leave their precise within-sector positions unknown. Since the distance depends on both positions, knowing the sectors alone cannot settle the angle question. This is a schematic explanation of how the input works, not an example of an actual chart or a claim about any particular pair. The important point is not that the positions must be far apart or close together, but that the sign label does not select one location within the sector. Many possible positions share that same sign name, and their separations from another placement can therefore differ.

Degrees add location, not a new sign meaning. With both values, the report page says it can calculate the shortest zodiac angle between the positions and check the configured aspect set. If either value is absent, that exact calculation is unavailable from the supplied information. There is no sound way to fill the gap by choosing a typical point in the sign or by assuming the center of the sector: either move would add a position the reader did not provide. Preserve the unknown instead. The comparison can still use the known signs at their own level, while the degree-dependent question remains open.

That separation is useful when deciding what to do with incomplete information. If the question concerns sign symbolism, sign names can still support a comparison. If it concerns the exact angular relationship, both positions matter. The product treats degrees as optional at intake, so a reader can leave them out rather than guess; the tradeoff is simply that the degree-based angle cannot be determined from sign names alone. This gives each input a precise job: signs identify the sectors for symbolic comparison, and degrees locate the placements for geometric comparison.

Which five angular targets does the report check?

The report checks five target angles: conjunction at 0°, sextile at 60°, square at 90°, trine at 120°, and opposition at 180°. A target angle is the exact separation between two planetary positions that the calculation tests. The public page, “Synastry Comparison Report,” says its shortest-angle calculation checks five major aspects when both degrees are supplied; it does not leave the target list open to inference from the names of the two planets. “Astrology Aspect Symbols and Meaning” lists the same five commonly named major aspects, while “Getting the Most from Your Professional Natal Report” discusses these familiar angular relationships in its technical guidance. Together, the sources establish the names and customary angle values, while the product page establishes that these are the five selected for this report’s calculation. The list therefore answers a narrow settings question: which exact angular targets are in the disclosed check? It does not claim to describe every aspect tradition or every relationship an astrologer might consider.

That distinction matters because “five major aspects” is a configured selection, not a boundary around all astrological practice. “Getting the Most from Your Professional Natal Report” also discusses additional aspect families, including minor aspects, and “Astrology Aspect Symbols and Meaning” is an explainer of a common five-aspect grouping rather than an exhaustive taxonomy. The existence of other named angles does not add them to this product’s stated calculation set. Nor does their omission mean those relationships have no place in other interpretive methods. The useful reading is specific: when the Synastry Comparison Report describes its five-aspect check, the five targets are conjunction, sextile, square, trine, and opposition at the angles listed above. A reader comparing its disclosed method with another chart reference should check which target set that reference uses instead of assuming that the word “major” settles every practitioner’s taxonomy. The angle identifies the geometric relationship being tested, while the name gives that relationship its conventional label; neither alone says how the contact will be interpreted. A contact can therefore be recognized as a square, for example, without treating the label as a complete reading of the two placements. Naming the set makes the report’s calculation scope reproducible; it does not rank unlisted families or supply their interpretations. Those are separate questions from which angles this calculation is configured to test.

What does the fixed 6° orb decide?

An orb is the tolerated distance from an exact target angle: it tells the calculation how far a separation may fall from exactness and still count as a match to that target. “Getting the Most from Your Professional Natal Report” uses orb in this technical sense and describes conventions that can vary with the aspect and the planets involved. The Synastry Comparison Report states a fixed 6° orb for its selected aspect check when both placements’ degrees are supplied. In this setting, six degrees is the product’s disclosed cutoff around each of its five targets, not a universal rule that every astrologer must use. Once the shortest separation has been compared with a target, the orb supplies the tolerance for deciding whether the candidate falls close enough to be included. It makes the report’s classification rule legible: a candidate within the allowed distance can be flagged as matching that selected target under this method; one beyond the allowed distance does not meet that report rule. The threshold concerns membership in the configured check, not the inherent worth of a placement or connection.

This is why the cutoff should be read as a calculation setting rather than an interpretation in itself. The product page, “Synastry Comparison Report,” describes the fixed tolerance and the conditions for applying the degree-based check; “Getting the Most from Your Professional Natal Report” shows that other astrological conventions may vary their orb allowances across aspect types or luminaries. That variation is a reason to name this report’s rule precisely, not to silently substitute another convention. The six-degree setting allows a consistent answer to a limited question: does the supplied pair fall within the report’s permitted distance of one of its five selected targets? It does not answer how prominent an astrologer should make that contact, what the symbolic reading should be, or how two people behave. Those judgments require interpretation after the geometric classification and depend on the framework being used. Two contacts that pass the same mechanical threshold need not receive identical emphasis, and a contact that falls outside this rule is not thereby declared meaningless in every astrological approach. For a reader, this separation prevents a technical inclusion label from being mistaken for a ranking of the whole comparison. The orb decides the report’s inclusion boundary; readers should keep that result distinct from interpretive weight.

What can an aspect label mean after it is identified?

An aspect label names a symbolic pattern to explore after the angle has been identified. In “The Meaning of the Aspects in Astrology,” Cafe Astrology presents five familiar patterns: a conjunction blends the functions involved; a sextile suggests an opening that can be used; a square brings tension that calls for action; a trine describes flow; and an opposition sets two functions in polarity. This is one practitioner vocabulary for reading the geometry, not an additional calculation made by the report. The label gives a starting question about how two planetary functions might meet in a chart comparison.

The sequence matters. First identify the planets and what each represents in the chosen interpretive framework. Then read the aspect as a pattern between those functions. Finally, return to the signs and the wider context to ask how that pattern might be expressed. A conjunction, for example, does not have a single emotional meaning independent of the planets it joins. The aspect supplies a relationship word, while the planets supply the functions being related. Signs can then qualify the style of that expression. Starting with the aspect adjective alone skips the material needed to make a specific interpretation.

This is why “easy” and “hard” can be too blunt as a complete reading. Flow may describe a quality that feels familiar, but familiarity does not by itself show what someone chooses to do with it. Tension can name friction or activity without proving that the contact is harmful. And an opening may invite engagement without ensuring that either person takes it. The shorthand compresses a symbolic distinction into a verdict about pleasantness, when the useful question is what the pattern asks the reader to notice. The cited practitioner account itself offers more textured terms: blending, opportunity, tension, flow and polarity.

Use those terms as prompts, not outcomes. For a conjunction, ask which functions seem to operate together; for a sextile, what opening might be available if engaged; for a square, where a difference could demand conscious adjustment; for a trine, what may come naturally and therefore go unexamined; for an opposition, what contrasting needs might require recognition on both sides. These are interpretive questions, not findings about a couple’s conduct or relationship success. Other astrologers may emphasize different facets, so this vocabulary should be named as one framework rather than treated as a universal key. The report’s geometric identification and the reader’s symbolic interpretation remain separate steps.

What can a sign comparison contribute without degrees?

A sign comparison can still describe symbolic tone through element and modality, two different groupings in the Western astrology framework presented in “The Elements in Astrology.” Element groups signs by a shared symbolic nature; modality groups them by a mode of expression or orientation. They answer different descriptive questions, so one sign can be considered through both classifications. The “Synastry Comparison Report” also describes sign-level comparisons as revealing elemental and modal themes. That gives a reader a way to discuss the supplied signs even when the optional degree information is unavailable, without turning the sign layer into an angular finding.

The distinction is useful because a shared category does not make two signs identical, and different categories do not decide whether a pairing is compatible. Element offers one broad vocabulary for the tone associated with a sign; modality offers another for how its style is framed. Read together, they can shape a more precise question than “Are these signs alike?” A reader might ask what kind of approach each sign symbolizes, whether the two approaches share a quality, and where their emphases differ. Those are interpretive comparisons of signs, not descriptions of the actual personalities or habits of the people who supplied them.

For example, imagine someone comparing two known signs and noticing that their modality categories suggest different ways of approaching a plan. As an illustrative conversation prompt, they might ask: when something new needs to begin, who tends to propose a first step; once underway, what helps each person sustain attention; and when circumstances change, how does each prefer to adapt? The example supplies no birth placements and reports no observed couple behavior. It turns the category into a question the people can answer from their own experience, rather than treating astrology as proof that either person will act in a particular way. If their answers differ from the symbolic prompt, their lived account is the relevant information for the conversation.

A sign-level reading therefore has a bounded use: it can organize reflection about symbolic tone and offer language for discussing differences or common ground. It cannot answer every chart question, and the element or modality label should not be mistaken for a complete interpretation of a person. Most specifically, sign categories do not establish an exact angular contact. At the same time, a missing degree does not erase the sign symbolism that is available. Keeping those contributions distinct lets readers use what they know without filling in what they do not: compare the signs at their symbolic level, and leave the geometry question for information that can support it.

What questions fall outside this report's selected placements?

A question falls outside this report’s selected placements when answering it depends on chart factors the report does not ask you to supply. Its focus is the Moon, Venus and Mars signs for two people, with optional degrees for the disclosed angle checks. That is a defined comparison lens. It does not make those three placements a complete account of synastry, nor does every relationship question require a wider reading. The useful test is whether the factor named in your question is among the information this comparison uses.

Broader references show why that test matters. In “Aspects Between Charts,” the interchart catalog ranges across combinations involving the Sun, Mercury, outer planets and points as well as Moon, Venus and Mars. “Synastry” also discusses signs, houses and additional chart contacts. These works demonstrate that practitioners may consider a much wider field; they do not establish a mandatory checklist or a single standard that every reading must follow. A longer factor list can create more interpretive material without making the answer to a particular question clearer.

Instead, name the question first, then identify the chart layer it actually depends on. If you want to compare the supplied Moon, Venus or Mars signs, this report’s selected placements may fit that bounded task. If your question is specifically about communication patterns, Mercury is an example of a relevant factor to investigate in a broader chart reference. If it depends on house placement, a comparison that does not request houses cannot settle it. Those are category examples, not claims about either person’s chart or about what a particular report output contains. The point is not to infer that any absent factor would change a reading, but to notice when the question itself names something the selected inputs cannot represent. A communication question may also involve lived conversation and circumstances; a planet label alone would not answer how two people actually communicate.

This gives you a practical scope rule: use the focused comparison when its stated inputs bear on your question; seek broader chart context when the missing factor is essential to the question you want answered. More factors are useful when they add the layer your question needs, not simply because more factors are available. A bounded question can be served by a bounded lens. A question whose subject lies beyond that lens should remain open until you consult a method that includes the relevant chart information.

The distinction between a focused lens and a complete chart reading also prevents two opposite mistakes. A reader need not reject a useful comparison just because it omits other factors, and should not treat its selected placements as if they settle every possible question. “Aspects Between Charts” and “Synastry” support the existence of broader interpretive material, while the report page defines the scope of this particular tool. The decision follows from matching the question to that scope, not from ranking one approach as universally superior.

What should I bring to the comparison?

Gather the Moon, Venus and Mars signs you already know for each person. Add degrees only where you have them; leave uncertain placements unknown rather than filling gaps with guesses. Then visit /compatibility-test and choose “Compare our placements” if the report’s selected inputs match the question you want to explore. If you need to know exactly which directional outputs the completed report displays, check the live product flow before relying on that detail: the public overview describes its inputs and method but does not enumerate every output. Before entering anything, separate what you know from what you do not. The live instructions allow known placements to be entered while uncertain ones remain unknown, so incomplete information does not need to be converted into a guess. Degrees are optional, and they matter for the report’s shortest-angle and aspect check only when both positions are supplied. If you are deciding whether the tool addresses your question, compare that question with the chosen Moon, Venus and Mars inputs first. Use the product flow when that scope fits. If your decision depends on whether a specific pair, direction or result card appears, confirm that detail in the live flow because the public overview does not list every output. That check answers a product-interface question; it does not require you to supply chart information you do not have.
