WebSep 8, 2012 · An ephemeris is a table of values that gives the positions of astronomical objects in the sky over a range of times, while geocentric means "as seen from Earth's center." The following table is a key to the geocentric ephemeris of the Moon and includes a description of each column in these tables. Calendar Date (Gregorian). WebMay 29, 2024 · geocentric latitude . (a) The latitude or angle at the center of the Earth between the plane of the celestial equator and a line (radius) to a given point on the Earth's surface. It would be identical with geodetic latitude only for a truly spherical Earth. Symbol: ψ. (b) The celestial latitude of a body based on or as seen from the Earth's center.

Geocentric coordinates can be used for locating astronomical objects in the Solar System in three dimensions along the Cartesian X, Y, and Z axes. They are differentiated from topocentric coordinates, which use the observer's location as the reference point for bearings in altitude and azimuth.
