| Suggested name | Zamyo |
| Planet type | Cold planet |
| Zamyo is the fourth planet from HD 131496 and the second-smallest planet in its solar system.
This planet is named after the deity Zamyo, the goddess of war.
Zamyo is gravitationally locked with HD 131496 in a 4:3 spin-orbit resonance, and rotates in a way that is unique in its solar system.
Two spacecraft have visited Zamyo: Wayfinder 3 flew by 36 years ago; and Messenger, launched 12 years ago, orbited Zamyo over 140 times in four years before exhausting its reactor and crashing into the planet's atmosphere 4 years later.
The smooth Borealis basin in the northern hemisphere covers 14 percent of the planet and may be a giant impact feature. |
