Once I drew a diagram called the "Ultimate Axis Under Two", which showed this: A spacecraft orbiting the moon of a moon, which is in a binary orbit with a second moon, which itself has another moon and spacecraft orbiting that second moon. Then, the two moons were orbiting a planet, which was orbiting around a dual star system. The stars are orbiting around the centre of the galaxy, and those around a cluster, and that around a supercluster, and around a black hole, which is going around the universe. Therefore, the original spacecraft is orbiting around 10 different axes, including its own centre of gravity. My science is probably at least slightly wrong, what with a cluster going around a supercluster and whatnot, but I don't care about the physics.
