On Earth, we can use latitude and longitude to fairly accurately describe a single point on the surface of the earth. This works because the earth is, for all intents and purposes, a sphere. It got me thinking about what kind of system, if any, we would use to describe a single point on the surface of a non-spheroid body, like a large asteroid or an oblong moon.
I suppose you could just "wrap" the object's topology to a spherical projection, though this would result in massive distortions. More importantly, it also raises the question of what the 'fixed points' are of the system (i.e. where are geographical north and south poles)? We've recently witnessed large asteroids and moons tumbling chaotically in their orbits with no discernible rotation axis.
