EPHEMERIS Meaning and
Definition
-
An ephemeris can be defined as a reference book or table that provides the positions and movements of celestial bodies, such as planets, stars, and other astronomical objects, at specific times or intervals. It is essentially a detailed almanac for astronomers and navigators, serving as a reliable tool to determine the precise positions of celestial bodies in the sky for various purposes.
The ephemeris typically includes crucial data such as the coordinates of celestial objects, their daily or monthly positions, and their apparent magnitudes. It accounts for the dynamic nature of these objects due to their orbits and gravitational interactions, allowing astronomers to accurately predict their locations at a given time.
One of the primary applications of an ephemeris is in celestial navigation, where it aids in determining the position of a ship or aircraft by using celestial bodies as a reference point. By consulting the ephemeris, navigators can calculate the angle between the horizon and a celestial body and thus pinpoint their location on Earth.
Additionally, ephemerides are indispensable tools for astronomers, planetary scientists, astrologers, and even amateur stargazers. They facilitate the planning and observation of celestial events, such as eclipses, conjunctions, and the transits of planets. Ephemerides have been developed and refined throughout history, contributing significantly to our understanding of the cosmos and the precise tracking of astronomical phenomena.

Etymology of EPHEMERIS
The word "ephemeris" is derived from the Greek word "ephēmeros" (ἐφήμερος), which means "diary" or "daily". It is a combination of "epi" (ἐπί), meaning "on" or "upon", and "hēmera" (ἡμέρα), meaning "day". The term originally referred to a daily record or journal, but it later became specifically associated with astronomical tables or almanacs that provide the positions of celestial objects at given times. In this context, an ephemeris is a reference work used to determine the precise locations of celestial bodies such as planets, stars, and comets on specific dates.
