Apparent Motion

(religion, spiritualism, and occult)

It has become astrological tradition to speak about the zodiac and the heavenly bodies as if they were revolving around the Earth while Earth remains stationary. So that other people do not regard astrology as locked in a pre-Copernican worldview, astrologers sometimes specify that they are talking about the apparent motion of the stars and planets. In this custom, astrologers are following the same tradition as everyone else who refers to the daily appearance and disappearance of the Sun—for example, as the “rising” and “setting” of the Sun—even though most people in industrialized societies know that it is the axial rotation of the Earth that causes this apparent motion.
