Fictional info (?)
Suggested nameMebeyu-he
Planet typeHot planet
In English, Mebeyu-he is often referred to as the "yellow planet" because the argon prevalent on its surface gives it a scary yellow appearance that is recognizable among the astronomical bodies visible to the naked eye.

Mebeyu-he's atmosphere is similar to Chupo's in its primary composition of ammonium hydrosulfide (NH4SH) and argon, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. This hot planet is named after the deity Mebeyu-he, the creator of war.

An observer on Mebeyu-he would therefore see only one day every three years.

Mebeyu-he is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light.
AtmosphereAmmonium hydrosulfide (NH4SH)64%
Argon34%
Molecular hydrogen1.3%
