Natal chart reference
Sun and Mars aspects
Sun-Mars aspects connect personal direction with initiative, effort and the way someone responds to a challenge. The conjunction concentrates these functions. The square and opposition bring competing priorities into view; the sextile and trine describe ways they can cooperate.

All five major angles are possible between the Sun and Mars. Each uses the same 6° natal limit in Astriel. The measured separation selects the contact.
- Sun conjunct Mars0°A personal aim quickly becomes something to act on
- Sun sextile Mars60°A chosen action can give a personal aim a practical start
- Sun square Mars90°The way you act can compete with the purpose behind it
- Sun trine Mars120°A familiar way of working can support personal direction
- Sun opposite Mars180°A personal direction and an immediate impulse need separate attention
A missing major aspect can mean the separation falls between these limits. Astriel also checks the 30° semisextile and 150° quincunx with 2° orbs.
Use the houses to name the subject
The Sun house locates an area of personal direction; the Mars house locates an area of action or assertion. Across calculated Placidus houses 5 and 9, creative direction connects with effort in study or teaching. The same signs can occupy different houses in another chart. Use the supplied cusp membership.
Other aspects can support or complicate the same topic. A Sun-Mars trine can coexist with a Sun-Saturn square. Neither contact removes the other.

Birth-time uncertainty and motion
A conditional aspect meets the selected limit for only part of the possible birth-time interval. Keep the orb range and status shown in your result.
Applying means the orb is decreasing; separating means it is increasing. Both bodies' calculated motion matters, including Mars's retrograde motion. A still diagram cannot supply that direction.
How uncertain times are handledA natal aspect is different from a Mars transit
This guide compares positions in one birth chart. A Mars transit compares moving Mars with a saved natal position and needs a chosen date.
