Sagittarius or Capricorn traits

If your Sun is in Sagittarius: You seek. Meaning, distance and the bigger picture pull you forward, and your honesty is a kind of generosity. The lesson of a Sagittarius Sun is that the journey also needs somewhere to land.

If your Sun is in Capricorn: You endure. Ambition, patience and a dry sense of humour carry you up long slopes other people give up on. A Capricorn Sun learns, eventually, that rest is part of the climb.

Your Sun sign is one part of a chart. The Moon and the rising sign, which need the time and place of birth, say as much about you. StarMap is for entertainment and self-reflection.

Signs are computed from the Sun’s position with the astronomy-engine ephemeris, checked against Swiss Ephemeris, for every year from 1900 to 2026. Birth dates and places come from Wikidata. A sign is shown beside a name only when it holds for the whole of the birth date; where it does not, both possibilities are given. How to read a birth chart.
