| Suggested name | Yuan |
| Planet type | Cold planet |
| Yuan 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. Yuan is orbiting Kepler-1542 every 6 Earth days. It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.
When viewed from Youl, Yuan 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. This planet is named after the deity Yuan, the bringer of love and beauty.
Plans have been proposed for rovers or more complex missions, but they are hindered by Yuan's hostile surface conditions.
Yuan is primarily composed of 2H2O with a significant part of its mass being hydrogen deuteride (HD), though hydrogen deuteride (HD) comprises only about a tiny fraction of the number of molecules. |
| Atmosphere | 2H2O | 55% |
| Hydrogen deuteride (HD) | 26% |
| Krypton | 16% |
| Ammonium hydrosulfide (NH4SH) | 1.3% |
| Carbon dioxide | 0.93% |
| Neon | 0.053% |
| Atmospheric pressure | 50 bar |
