Fictional info (?)
Suggested nameCojaod-atwei
Planet typeLarge cold gas giant
In English, Cojaod-atwei is often referred to as the "green planet" because the hydrogen deuteride (HD) prevalent on its surface gives it a dark green appearance that is unusual among the astronomical bodies visible to the naked eye. 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.

It is named after the deity Cojaod-atwei, the creator of the sky.

At this time it may appear as a bright star-like object, but is often far more difficult to observe than Yuegang Zh.

It is radically different from Yuegang Zh in other respects. Cojaod-atwei is by far the hottest planet in its solar system, with a mean surface temperature of 718°K (445°C).

It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
