Other Synchronous Orbits
Synchronous orbits exist around all moons, planets, stars, and black holes — unless they rotate so slowly that the orbit would be outside their Hill sphere or so fast that such an orbit would be inside the body. Most inner moons of planets have synchronous rotation, so their synchronous orbits are, in practice, limited to their leading and trailing (L4 and L5) Lagrange points, as well as the L1 and L2 Lagrange points, assuming they do not fall within the body of the moon. Objects with chaotic rotations (such as exhibited by Hyperion) are also problematic, as their synchronous orbits change unpredictably.

Famous quotes containing the word orbits:
“To me, however, the question of the times resolved itself into a practical question of the conduct of life. How shall I live? We are incompetent to solve the times. Our geometry cannot span the huge orbits of the prevailing ideas, behold their return, and reconcile their opposition. We can only obey our own polarity.”
—Ralph Waldo Emerson (1803–1882)
