An
ephemeris (plural:
ephemerides) is a table providing the apparent positions of the
sun, the
moon, and the
planets in the sky at a given moment in time, at a given point on the earth. It also provides data on
astronomical phenomena of interest to
astrologers such as solar and lunar
eclipse, apparent retrogradation, planetary ingress,
sidereal time and positions for the nodes of the moon.
