Definition:Celestial

Definition
In the context of astronomy, the word celestial is an adjective whose meaning is loosely of the sky.

It is used to define bodies and phenomena vaguely defined as being outside Earth's atmosphere, hence does not apply to meteorological phenomena.

It is often used as an antithesis for the word terrestrial, which means of Earth.
