Formerly known as P4 and P5, Pluto’s tiniest moons now have official names: Kerberos and Styx.
The names were among the top three selected by voters during a two-week polling period; they have just been approved by the International Astronomical Union’s official nomenclature committee.
Thus, from this day forward, the two tiniest of rocks orbiting the overgrown-snowball-formerly-known-as-a-planet will conjure the tales of a three-headed dog guarding the gates of the underworld (Kerberos), and the river that doomed souls must cross (Styx).
