| Suggested name | Tyuan |
| Planet type | Hot planet |
| The planet is named after the deity Tyuan, the goddess of war.
When viewed from Earth, this proximity to Kepler-256 means the planet can only be seen near the western or eastern horizon during the early evening or early morning.
Tyuan is gravitationally locked with Kepler-256 in a 4:3 spin-orbit resonance, and rotates in a way that is unique in its solar system.
It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
The latest probe to visit the planet is Racer, which entered into orbit around Tyuan after a challenging ride. |
