Two-chart reference
Venus trine Mars in synastry
A Venus-Mars trine connects positions near 120° apart. Its traditional theme is ease between one person's way of showing affection and the other's way of taking initiative.
120° exact angle · 5° maximum synastry orb in Astriel
Compare two birth chartsAn easy response to an invitation
An approach can fit a preference without much explanation. In an in-sign trine, the signs share an element, which supplies a common style. Ease can also leave preferences unspoken. A familiar routine needs to remain welcome as both people's circumstances change.
These are symbolic interpretations. The contact cannot establish attraction, consent or commitment, and the planetary roles do not describe gender.
A's Venus trine B's Mars
Person A is the first person entered in the calculator. This contact compares A's preferences with B's initiative.
Worked example
A's Venus at 10° Virgo and B's Mars at 12° Capricorn are 122° apart, a 2° orb. A appreciates practical care; B organizes the steps for a shared project. Both earth signs give the example a focus on usefulness and tangible effort.
A's Mars trine B's Venus
With A's Mars in Capricorn and B's Venus in Virgo, A organizes the work and B supplies the appreciation of practical detail. Changing the owners changes the perspective even though the same aspect name applies.
If both directions appear, read them separately. Each contact has its own angle and birth-time certainty.
Read affection beside emotional needs
Venus-Mars concerns appreciation and action. Moon contacts introduce comfort and emotional responses; Mercury contacts concern how the two people exchange ideas.
An easy Venus-Mars contact can coexist with a difficult conversation. Read each person's natal Venus and Mars before interpreting how they respond to the other chart.
Compare relationship chart methodsCheck the degrees and the birth-time range
Orb measures how far the smaller separation falls from the exact 120° angle. Astriel includes this contact at an orb of 5° or less.
The positions above are teaching examples. Sharing signs does not establish an aspect; the degrees decide whether it fits the rule.
When the birth time is uncertain
A conditional contact fits the allowed orb during only part of the possible birth-time range. Another time within that range can put it outside the limit.
A contact can also stay within the limit throughout the available range while its exact orb changes. Neither status measures relationship quality.
Source and method
Symbolic meanings follow the owner-supplied astrology reference, Part VI, Venus interaspects and aspect modes. Examples are original. Orb limits follow Astriel's computed synastry method rather than the reference's suggested orb table.
These contacts belong to two separate birth charts. A composite uses planetary midpoints and answers a different chart question.
