Celestial Bodies

: an aggregation of matter in the universe (such as a planet, star, or nebula) that can be considered as a single unit (as for astronomical study)

But many scientists began seriously rethinking their notions of the solar system in 1992, when we identified a small celestial body—just a few hundred kilometers across—sited farther from the sun than any of the known planets.

As the observer looks at a star or other celestial body its light rays pass through a single point on the earth's surface.

A black hole forms when a star or other celestial object collapses under the pull of its own gravity.
