astronomical object

Astronomical object is one of the general terms for an object in space such as a star, planet (or SSSB), or meteoroid, or something less solid such as a galaxy or cloud. Other terms are celestial body and astronomical body, but each suggests some particular characteristics: "body" perhaps suggests an object more distinct than a cloud, such as a planet or star, and "celestial" perhaps suggests something observable in the sky (i.e., the celestial sphere) though the terms are not always used in these respects. For some of the types of astronomical objects, see list of object types.
