| Suggested name | Nigena |
| Planet type | Cold planet |
| It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 75°K (-198°C), and has a complex, layered cloud structure with helium thought to make up the lowest clouds, and methane the uppermost layer of clouds. This cold planet is named after the deity Nigena, the demon of the sky.
As seen from Kepler-385, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.
Plans have been proposed for rovers or more complex missions, but they are hindered by Nigena's hazardous precipitation.
Because of its rapid rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator).
In late February 2500, Nigena was visited by the New Horizons probe, which used Nigena's gravity to increase its speed and bend its trajectory en route to Cokor.
Its north and south poles, therefore, lie where most other planets have their equators. |
