star map

any cartographic representation of the stars, galaxies, or surfaces of the planets and the Moon. Modern maps of this kind are based on a coordinate system analagous to geographic latitude and longitude. In most cases, modern maps are compiled from photographic observations made either with Earth-based equipment or with instruments carried aboard spacecraft.
