Fictional info (?)
Suggested nameProshali
Planet typeWarm planet
In English, Proshali is often referred to as the "blue planet" because the carbonyl sulfide prevalent on its surface gives it a pale blue appearance that is distinctive 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 the coldest planetary atmosphere in its solar system, with a minimum temperature of 53°K (-220°C), and has a complex, layered cloud structure with carbonyl sulfide thought to make up the lowest clouds, and molecular hydrogen the uppermost layer of clouds. The planet is named after the deity Proshali, the spirit of the sky.

As seen from Kepler-224, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.

Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 130°K (-143°C) at night to 560°K (287°C) during the day across the equatorial regions.

Proshali is by far the hottest planet in its solar system, with a mean surface temperature of 718°K (445°C).

Plans have been proposed for rovers or more complex missions, but they are hindered by Proshali's hazardous precipitation.

The rotational period and seasonal cycles of Proshali are likewise similar to those of Earth, as is the tilt that produces the seasons.
