Celestial motion is endless while surface motion terminates.

Evidence

Endless motions are those which have place among the bodies, (each of them considered in its totality,) of which the visible universe is composed. … To the class of terminating or terminative motions belong all those which have place in our planet, and, to judge from analogy, all those which have place in any other of the celestial bodies. — Jeremy Bentham, The Panopticon Writings, 544
