Interamnia
The fifth-largest asteroid, here for its size and for very little else that is known: no spacecraft has been to it, it has no moon, and even its shape had to be worked out from how starlight blinks off when it passes in front of one. It is dark, carbon-rich and about a third the width of Ceres.
