many astronomers consider pluto and charon to be a binary system, but two small bodies orbit that system. they are called nix and hydra.
incidentally, "134340 pluto" was never a moon of neptune. neptune did capture triton. this is why triton has a retrograde orbit. also, "13199 eris" is about five percent bigger than "134340 pluto".

Pluto has three known natural satellites: Charon, first identified in 1978 by astronomer James Christy; and two smaller moons, Nix and Hydra, both discovered in 2005.

It has been disputed whether or not pluto and its largest "moon" are "co-moons" or something. They have been found to orbit each other because they are very close to being the same size.

3. Charon, which was discovered in the late 70s, and Nix and Hydra, which were just discovered this year. (It was announced in June, so a lot of people haven't heard about it yet.)
Nix and Hydra are puny little things, whereas Charon is roughly half the size of Pluto.
