WebFor precise solar system work it is necessary to distinguish between geocentric coordinates (centered at the center of the Earth) and topocentric coordinates (centered at the observer on the Earth's surface). This distinction is not trivial, for the Earth's diameter subtends an angle of 16″ at an distance of 1 AU. WebApr 8, 2024 · A system of coordinates with their origin at a point on the Earth's surface. For objects in the Solar System there are slight differences between topocentric and geocentric coordinates that must be allowed for in precise measurements, but for more distant objects such as stars and galaxies there is no detectable difference.
