| Suggested name | Erys |
| Planet type | Cold planet |
| Erys is similar in composition to Alener, and both have different bulk chemical composition from that of the larger cold planets. This cold planet is named after the deity Erys, the messenger of war.
At this time it may appear as a bright star-like object, but is often far more difficult to observe than Alener.
Erys is gravitationally locked with HIP 56640 in a 4:3 spin-orbit resonance, and rotates in a way that is unique in its solar system.
Erys is the site of Robusto Mons, the most active volcano and second-highest known mountain in its solar system, and of Valles Marineris, one of the largest canyons in its solar system.
Observations from Earth have shown seasonal change and increased weather activity as Erys approached its equinox 3 years ago. |
