The moon of Makemake

Makemake and moonAstronomers reveal that Makemake, an icy dwarf planet orbiting in the distant Kuiper Belt region of the solar system, has a moon, first spotted in 2015 by a team using the Hubble Space Telescope. (The news comes just days after the 26th anniversary of Hubble’s launch.) With an estimated diameter of 100 miles (compared to the 870 mile diameter of its parent body), the satellite orbits Makemake at a distance of 13,000 miles, taking twelve days to complete one orbit. Previous observations failed to pick up on the dark, dim body due to the relatively bright glare of Makemake itself.
