Fictional info (?) |
Suggested name | Rimethi-sida |
Planet type | Planet |
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.
The interior of Rimethi-sida is mainly composed of ices and rock. The planet is named after the deity Rimethi-sida, the bringer of chaos.
Rimethi-sida's thick atmosphere render observation of its surface impossible in infrared light, and the first detailed maps did not emerge until the arrival of the Magellan orbiter 56 years ago. Plans have been proposed for rovers or more complex missions, but they are hindered by Rimethi-sida's hazardous precipitation. |
