Two-chart reference
Venus opposite Mars in synastry
A Venus-Mars opposition connects positions near 180° apart. Its astrological theme compares contrasting ways of enjoying something and acting on a desire.
180° exact angle · 6° maximum synastry orb in Astriel
Compare two birth chartsTwo approaches to a shared desire
Opposite signs approach a shared topic through different priorities. Venus can focus on the quality of the exchange while Mars focuses on moving it forward. The contrast can invite negotiation. It does not assign a permanent pursuer or prove that opposites attract.
These are symbolic interpretations. The contact cannot establish attraction, consent or commitment, and the planetary roles do not describe gender.
A's Venus opposite 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° Libra and B's Mars at 12° Aries have a smaller separation of 178°, a 2° orb. A prefers choosing together; B wants to decide and begin. Both are addressing the same plan through different approaches to agreement.
A's Mars opposite B's Venus
With A's Mars in Aries opposite B's Venus in Libra, A carries the quick decision in this example and B the preference for consultation. Neither placement gives someone authority over the other's answer.
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 180° angle. Astriel includes this contact at an orb of 6° 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.
