Pluto is now at opposition; it’s opposite the sun’s position in the sky. This distant world rises at sunset and sets at dawn, shining as a very faint, 14th magnitude “star”, in the direction of the northeast end of the constellation Sagittarius the Archer. Tonight it’s about midway between the moon to the left and bright, star-like Saturn to the right; but you can’t see Pluto without a really good telescope, and even then it only appears as a dim star. Pluto has five moons - Charon, discovered in 1978, is roughly half the size of Pluto. The other four moons, are Nix, Hydra, Kerberos and Styx. In mythology, Pluto was the god of the underworld, and its moons are part of the myth: Charon was the son of Nyx, the goddess of the night, and he was the ferryman who took souls across the river Styx to Pluto’s realm, which was guarded by the multi-headed Hydra. There you could pet his three-headed dog Cerberus, or in this case it’s the Greek name Kerberos, because somebody already named an asteroid Cerberus.
