An astronomical object, celestial object, stellar object or heavenly body is a naturally occurring physical entity, association, or structure that exists within the observable universe. [1] In astronomy , the terms object and body are often used interchangeably.
The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following reference. [58] Asteroid spectral types are mostly Tholen, but some might be SMASS.
This list contains natural objects up to apparent magnitude 3.5. All objects are listed by their visual magnitudes, and objects too close together to be distinguished are listed jointly. Objects are listed by their proper names or their most commonly used stellar designation. This list does not include transient objects such as comets, or ...
Objects may have been discovered without distance determination, and were found subsequently to be the most distant known at that time. However, object must have been named or described. An object like OJ 287 is ignored even though it was detected as early as 1891 using photographic plates, but ignored until the advent of radiotelescopes.
