Suggested nameRionnand
Planet typeCold planet
Its orbital period around Kepler-1302 of 8.8 earth days is the longest of all the planets in its solar system.

It is named after the deity Rionnand, the bringer of good fortune.

It is radically different from Earth in other respects. It has the densest atmosphere of all the cold planets, consisting partly of methane.

The smooth Borealis basin in the northern hemisphere covers 35 percent of the planet and may be a giant impact feature.

The two polar ice caps appear to be made largely of ice.

Rionnand is primarily composed of methane with a significant part of its mass being ozone, though ozone comprises only about a tiny fraction of the number of molecules.
