astronomical objects
Stars and planets
Astronomical objects are natural bodies in space—stars, planets, moons, asteroids, comets, galaxies, nebulae, and black holes.
The term encompasses everything from dust particles to galaxy clusters, distinguished from artificial satellites and spacecraft.
In scientific contexts, the phrase often appears in discussions of observation and cataloguing: The telescope detected several previously unknown astronomical objects.
