late 14c., “the eye socket,” from Old French orbite or directly from Medieval Latin orbita, transferred use of Latin orbita “wheel track, beaten path, rut, course, orbit” (see orb).

1946, from orbit (n.). Related: Orbited; orbiting.
orbit or·bit (ôr’bĭt)
See orbital cavity.
In astronomy, the path followed by an object revolving around another object, under the influence of gravitation (see satellite). In physics, the path followed by an electron within an atom. The planets follow elliptical orbits around the sun (see ellipse).
Note: Informally, something is “in orbit” when its actions are controlled by an external agency or force: “The countries of eastern Europe were once in the orbit of the Soviet Union.”
