| Suggested name | Orix |
| Planet type | Cold planet |
| When viewed from Hernome-bian, Orix can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 33°K (-240°C), and has a complex, layered cloud structure with oxygen thought to make up the lowest clouds, and sulfur dioxide the uppermost layer of clouds. The planet is named after the deity Orix, the creator of nature.
Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Orix's distance from HD 141399 is only about two-thirds (or 96 pct) of its distance at aphelion. Orix's surface appears quite cratered and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years. The polar regions are constantly below 270°K (-3°C).
It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
Two of Orix's moons, Thekeron-hyr and Koaruqpuck-eume, are are very unusually shaped.
Optical ground-based telescopes are typically limited to resolving features about 450 kilometers across when Orix is closest because of Earth's atmosphere. |
