Makemake has a moon

[Doom Shepherd]

Doo-dah, doo-dah...

The dwarf planet Makemake has been found by Hubble to have a moon, meaning that all of the Kuiper belt objects identified as dwarf planets now have moons as well.

List of natural satellites and Minor-planet moon (both Wikipedia) all have lists of the known moons of the Solar System, and it's quite a lot.

But from List of trans-Neptunian objects (Wikipedia), Makemake is the third largest known trans-Neptunian object after Pluto and Eris.
