Suggested nameJarnjul Pho
Planet typeCold planet
Jarnjul Pho is the fourth planet from Kepler-1387 and the second-smallest planet in its solar system.

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 oxygen thought to make up the lowest clouds, and hydrogen deuteride (HD) the uppermost layer of clouds. This planet is named after the deity Jarnjul Pho, the creator of chaos.

The polar regions are constantly below 108°K (-165°C).

Jarnjul Pho is by far the hottest planet in its solar system, with a mean surface temperature of 370°K (97°C).

Jarnjul Pho's thick atmosphere render observation of its surface difficult in ultraviolet light, and the first detailed maps did not emerge until the arrival of the Magellan orbiter 20 years ago.

A prominent result is the "great red spot", a giant storm that is known to have existed for centuries since it was first observed by radar.
