Facts about the Dwarf Planet Makemake

Makemake has no moons:
Makemake is the largest of the Kuiper belt objects and the only one without satellites. Although we know its diameter to be about 2/3 that of Pluto, its mass can merely be estimated in the absence of nearby objects.

Makemake lacks its expected atmosphere:
Astronomers thought Makemake would have developed an atmosphere similar to Pluto’s, its chance passing in front of a bright star in 2011 revealed it mostly lacks a gas envelope. If present, Makemake’s atmosphere would likley be methane and nitrogen-based.
