Mars
Drive
Desire and the impulse to act. This is symbolic reading language; your actual placement comes from your birth details.
Find Mars in my chartMars describes the act of pursuing or resisting
Mars concerns the movement toward something wanted, and the effort used to protect a boundary. Competition and anger belong to its symbolic range, alongside initiative and the willingness to act.
The sign describes an approach to action. Aries emphasizes immediate initiative; Capricorn emphasizes planning and sustained effort. These are conventional readings, not measures of strength or proof of how someone handles conflict.
Mars aspects connect assertion with other functions. A contact with Mercury brings communication into the picture. A contact with the Moon brings emotional responses. The aspect type describes their symbolic relationship, while the orb states the measured separation from the exact angle.
A worked comparison
The house changes the reading
Mars in the 3rd can be read through debate or urgent communication. Mars in the 4th places the same function in home and private life. A claim that either person is aggressive would require evidence about their behaviour.
This is an illustrative reading, not a description calculated for you.

Mars's sign and degree
The sign identifies a 30-degree section of the tropical zodiac; the degree locates Mars inside it. A position near the end of a sign still belongs to that sign until it crosses the boundary.
The other planet and permitted orb matter when reading a Mars aspect. A sign pairing alone is not the computed contact.
Explore the zodiac signsHouse placement and birth time
Astriel defaults to Placidus. Find Mars between its calculated starting cusp and the next cusp. The birth time and location determine those boundaries. A sign name alone cannot identify the house.
With an approximate or unknown time, houses remain unavailable. Planetary signs and ranges can still be shown; missing house data is not a missing area of life.

Look for contacts involving Mars in the aspect table. The other factor, angle and allowed orb all matter. An aspect label describes a calculated relationship, not an event that must happen.

Traditional and modern rulership
Mars traditionally rules Aries and Scorpio. If one of these is your rising sign, Mars is your chart ruler under Astriel's method.
A ruler relationship does not tell you the planet's actual sign, house or strength.
