Orcus
A large Kuiper belt object on almost exactly Pluto's orbit - the same 2:3 lock with Neptune, the same tilt, the same period - but on the opposite side of it, which is why it is sometimes called the anti-Pluto. It is here for its size. Its moon Vanth is unusually large next to it, closer to a double body than to a planet with a satellite, and its surface carries water ice, which means something has resurfaced it.
