Over centuries the constellation and its symbolic twins were incorporated into Hellenistic and later Western astrological systems. The distinction between the astronomical constellation and the astrological sign arises because of precession and different zodiac frameworks.

Astrologers interpret the sign in natal charts, where the Sun in Gemini is only one factor among many in evaluating a chart.
