A minor aspect earns main-text attention when it is close by degree, joins a meaningful planet or angle, and explains a pattern the rest of the synastry has already begun to show. Treat it as background when it is wide, isolated, attached to a secondary point, or impossible to recognize in the relationship. Start with major contacts between the Sun, Moon, Venus, Mars, and reliable angles. Then check the exact separation. For this guide, read minor aspects most closely under 1 degree, and keep contacts from 1 to 2 degrees only when the planets or pattern support them. A 0°44' Venus-Saturn quincunx may clarify how affection and responsibility need translation. It does not outrank a close major contact just because its name looks unusual. Keep the aspect if it changes the story. Reduce it to a note if it only repeats one.
Why a full aspect list can blur the reading
A synastry report puts two horoscopes into conversation. That creates more contacts than most readers need at once. The aspect table can make every line look equally official, even though a conjunction, square, or trine usually carries the main structure and a minor aspect works more quietly. Nicholas Campion's guide makes the same broad distinction: major aspects are generally stronger, while minor aspects can refine the picture when an astrologer gives them a reason to speak.
An aspect is the angular distance between two chart factors. Common minor angles include the semi-sextile at 30 degrees, semi-square at 45 degrees, quintile at 72 degrees, sesquiquadrate at 135 degrees, and quincunx at 150 degrees. The angle describes the way two functions meet. It doesn't decide how much space the contact deserves.
That is the useful meaning of minor. It describes rank, not worthlessness. A small contact may explain the adjustment inside a larger pattern, the talent a couple shares, or the irritation that never becomes a full argument. Start with one sentence about the major pattern. Bring in a minor aspect only when it sharpens that sentence or explains what it leaves unresolved.
Your question sets the doorway. If you're trying to understand emotional timing, begin with Moon contacts. If you're asking about attraction or initiative, begin with Venus and Mars. A minor Mercury contact shouldn't take over simply because software lists it first.

Use degree distance as the first gate
An orb is the distance between the actual separation of two planets and the exact angle of their aspect. If two planets are 46°10' apart, their semi-square has a 1°10' orb. The smaller that distance, the more confidently you can examine the contact. Skyscript's orb glossary gives about 2 degrees as a common allowance for minor aspects, with wider allowances for the strongest major aspects.
For this decision guide, use a narrower working scale. Under 1°00' means investigate closely. From 1°01' to 2°00' means keep the contact only when the planets are central or the theme repeats. Beyond 2 degrees, place it in the notes unless your chosen tradition gives a clear reason to use it. This is a ranking rule for a supplied comparison, not a universal law of astrology.
Write degrees and minutes when you have them. A 0°59' contact and a 1°58' contact both fall inside two degrees, but they don't deserve the same volume. If degrees are missing, discuss sign relationships but don't claim a minor aspect falls within a particular orb.
Check the geometry first. Convert each placement to 0° to 360° longitude, find the shorter separation, and compare it with the exact angle. A quincunx at 149°16' sits 0°44' from exact; one at 152°40' sits 2°40' away. Identical labels do not make identical readings.
Applying and separating aspects can add a shade of emphasis in traditions that use planetary motion, but a static synastry comparison is not a clock. Establish the degree relationship, then decide whether it deserves interpretation.

Let the planets set the subject
Once a minor aspect passes the degree gate, name the planets before you name the problem. The Moon brings emotional response, comfort, memory, and the need to feel safe. Venus describes affection, pleasure, attraction, taste, and value. Mars brings desire, initiative, anger, pursuit, and repair after conflict. Mercury concerns words and exchange. Saturn adds duty, limits, fear, and endurance.
Then name the aspect's action. A semi-square can add pressure. A quincunx can ask for adjustment between functions that don't share an easy rhythm. A semi-sextile can require translation between neighboring styles. A quintile can point to a creative or problem-solving link. The planets tell you what is meeting; the angle tells you how.
A close Moon-Venus semi-square might show affection arriving in the wrong form or at the wrong moment. One person wants reassurance while the other offers charm, touch, or a pleasant distraction. Keep that reading only if the pair recognizes the exchange.
A close Mercury-Mars quintile asks a different question. Perhaps the couple solves practical problems quickly, teases each other into clarity, or finds an inventive way through conflict. It doesn't promise easy communication. It gives you a possibility to test.
If Alex's Mars contacts Maria's Venus, ask how Alex's initiative meets Maria's way of receiving affection. Then reverse the question. Synastry describes an exchange, not a verdict about who is right.

Look for a theme, not a second vote
A minor aspect gains weight when it echoes something already visible. A Venus-Mars semi-square beside a Venus-Mars square can describe the fine texture of attraction and friction. A Moon-Saturn quincunx beside a Moon-Saturn opposition can show the small adjustments inside a larger care-and-duty tension. The minor contact adds detail. It doesn't count as a separate vote.
Repetition can run through planets, signs, houses, or behavior. A Moon-Mars contact may echo different conflict speeds. A Venus-Saturn contact may become clearer when the same planets connect elsewhere, or when the couple keeps meeting the same question about affection and responsibility. House overlays belong here only when reliable birth times make them usable.
Deduplicate the data. Venus semi-square Mars and Mars semi-square Venus describe one inter-chart relationship, not two contacts. A software report can also split one relationship into applying and separating entries. Formatting is not repetition.
Use the deletion test. Remove the minor aspect from the draft. If the reading loses an explanation the couple needs, keep it. If the draft stays clear, reduce it to a note or remove it. Technical validity gets a contact onto the page. Necessity earns it a place in the reading.
A sign relationship may give the contact color, but it can't rescue a wide or isolated aspect. Preserve disagreement between layers when one exists. A minor aspect should refine the pattern, not force every part of the chart to agree.

The meaningful exception is close and personal
Repetition helps, but it isn't required in every case. A very close contact to the Sun, Moon, Venus, Mars, or a dependable angle can stand alone when the couple recognizes its subject in a concrete scene. A 0°12' Moon-Venus semi-sextile may describe a fine difference between emotional comfort and affectionate style. One person notices tone and presence. The other reaches through touch, beauty, or a small act of pleasure.
The exception stays narrow. Exactness and planetary relevance are doing work together. An angle contact needs a reliable birth time. If the time is uncertain, the angle may shift or disappear, so let reliable planetary contacts lead.
Nodes, asteroids, and calculated points can become meaningful in a focused reading, but they belong later in the first pass. A striking contact to a secondary point should not outrank a close Moon, Venus, or Mars contact merely because it feels dramatic.
Recognition must be specific. Ask when the pattern appears, what each person does, and what changes the exchange. 'We have a strange bond' is not enough. 'After conflict, I need warmth before solutions, while you offer solutions as proof of care' gives the aspect somewhere to land. If no scene emerges, lower the volume.

Worked example: a Venus-Saturn quincunx
Consider an example. Maria's Venus is at 14°02' Cancer. Alex's Saturn is at 13°18' Sagittarius. Their placements are 149°16' apart, which gives a 0°44' quincunx. These are illustrative supplied positions, not a calculated personal chart. State the placements, calculate the separation, name the orb, and read the contact through the wider comparison.
Venus in this example seeks warmth, emotional presence, and affection that feels dependable. Saturn in Sagittarius may express responsibility through principles, timing, distance, or a firm idea of the future. The quincunx places love and duty in different rhythms. It doesn't make either person wrong.
This contact earns a closer look because it is exact and because Venus and Saturn matter in relationship work. If major contacts also show closeness, restraint, or different expectations, the quincunx may describe how the couple translates affection into commitment.
In daily life, Maria might ask for a softer response after a difficult day while Alex answers with a five-year plan. The plan may be sincere. It still misses the first request. Or Alex may ask for room to explore a shared future while Maria hears uncertainty. The useful translation is practical: comfort first, planning second; freedom with a clear return point; affection that doesn't have to pass an exam.
Move the same placements to a 2°18' quincunx. The sign story remains interesting, but degree distance no longer carries the contact. Keep it if the couple describes the same pattern or the wider chart repeats it. Otherwise, keep the sign contrast as reflection, not as the main aspect.

Give the reader a clear place to put the aspect
A useful report shows its inputs. Record the supplied planets or points, signs and degrees, exact aspect angle, orb, and reason the contact survived review. If birth information is incomplete, leave houses and angles outside the claim. A placement comparison can still discuss known planets, but its scope is smaller.
Read in layers. Summarize major contacts first. Name the central relationship question. Then add only minor contacts that change the answer. For the Synastry Comparison Report, selected major aspects use a six-degree orb, while minor contacts follow the narrower working scale here. The report uses supplied placements and optional degrees. It doesn't calculate a natal chart from birth details, calculate houses, or produce a compatibility score.
Give each retained contact one job. A main-text aspect should clarify the central pattern. A secondary contact can sit in a nuance note. A valid but unnecessary contact belongs in working notes. For example: 'Venus quincunx Saturn, 0°44', affection and duty, ask how reassurance and responsibility can coexist.' One line carries the evidence and the next question.
When two reports disagree, compare inputs and rules before comparing prose. Check zodiac reference, degrees, aspect angles, orb thresholds, included points, and birth-time assumptions. One report may list a 3-degree quincunx while another uses 1.5 degrees. That is a method difference.
End with an action the couple can observe. Try a pause before problem-solving. Name the form of affection each person can feel. Keep the aspect when that question changes attention or behavior. Omit it when it only makes the chart busier.

A little more clarity
What orb should you use for a minor aspect in synastry?
Use a narrow orb, usually about 1 to 2 degrees for common minor aspects. Treat contacts under 1 degree as the strongest candidates, and keep a 1 to 2 degree contact when the planets are personal or the theme repeats elsewhere. State your rule and apply it consistently. A wide minor aspect shouldn't outrank a close major aspect just because it appears in the table. If degree data is missing, discuss the placements by sign and mark the exact aspect as unconfirmed.
