Orbit is also a word for an eye socket.

Planetary orbits

Two bodies with a slight difference in mass orbiting around a common barycenter. This is like the Pluto-Charon system

An orbit is the path that an object takes in space when it goes around a star, a planet, or a moon. It can also be used as a verb. For instance: “The earth orbits around the Sun.” The word ‘revolves’ has the same meaning, but 'rotates' is the spin of the object.
