| Suggested name | Erepu |
| Planet type | Cold planet |
| This cold planet is named after the deity Erepu, the goddess of the underworld.
Erepu's surface is a arid desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.
Erepu has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Daedalus flyby missions and later by the Hotchins orbiter. In late February 1100, Erepu was visited by the New Horizons probe, which used Erepu's gravity to increase its speed and bend its trajectory en route to Bono. |
