Fictional info (?)
Suggested nameYush'weiy Yun
Planet typeHot planet
For this reason, scientists often classify Yush'weiy Yun and Coywu Dyongb as "hot planets" to distinguish them from the other planets. This planet is named after the deity Yush'weiy Yun, the demon of destruction.

Yush'weiy Yun is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light.

Yush'weiy Yun was one of the first planets to have its motions plotted across the sky - as early as the second millennium BC.

Yush'weiy Yun is primarily composed of ethane with a significant part of its mass being carbonyl sulfide, though carbonyl sulfide comprises only about a small fraction of the number of molecules. A prominent result is the "great gray spot", a giant storm that is known to have existed for centuries since it was first detected by scanner.

The Yush'weiy Yun system has a unique configuration among those of the planets because its axis of rotation is tilted sideways, nearly into the plane of its solar orbit.
