American Ephemeris

The ephemeris">American Ephemeris is a series of astronomical tables that provide precise positions of celestial bodies, such as planets and the Moon, at regular intervals throughout the year. They are used by astronomers, navigators, and astrologers to understand the movement of these objects in the sky. The data helps in calculations related to timekeeping, navigation, and celestial events. First published in the 19th century, the tables are regularly updated to reflect improvements in our understanding of celestial mechanics and provide accurate information for various applications.
