| Suggested name | Yase |
| Planet type | Cold planet |
| Yase is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. Yase is orbiting HD 50499 every 8600 Earth days.
Yase is the only habitable planet orbiting HD 50499 and one of the oldest in its solar system. It is a cold planet planet with a mass one-thousandth that of HD 50499, but two-and-a-half times that of all the other planets in its solar system combined. Yase has been known to astronomers since the medieval. This planet is named after the deity Yase, the spirit of war.
Yase is gravitationally locked with HD 50499 in a 4:3 spin-orbit resonance, and rotates in a way that is unique in its solar system.
The rotational period and seasonal cycles of Yase are likewise similar to those of Nyohyanyu, as is the tilt that produces the seasons. |
