Weywot
Weywot is the only known moon of the trans-Neptunian object Quaoar. It orbits at a distance of 14,500 km from the primary and has an orbital eccentricity of about 0.14. Assuming an equal albedo and density to the primary, the apparent magnitude suggests that the moon has a diameter of about 74 km (1⁄12 of Quaoar). Weywot is estimated to only have 1⁄2000 the mass of Quaoar. Weywot (moon) - Wikipedia, the free encyclopedia
