Fixed stars in your chart

Long before the outer planets were discovered, astrologers paid close attention to the bright fixed stars. A star close to a planet or angle of your birth chart is said to colour it strongly, for better or worse. This calculator checks 41 major stars, including the four royal stars of Persia (Aldebaran, Regulus, Antares and Fomalhaut), and corrects their positions for precession to your year of birth.
