Chohe

Mass Effect & Mass Effect 3
Chohe is a terrestrial planet whose surface is mainly composed of aluminium, with numerous deposits of calcium. Though it has enough mass to retain a dense atmosphere, Chohe is nearly a vacuum. This lack of atmosphere allows a moderate average temperature, but the differences between day and night are extreme.

The surface of Chohe's sunward-facing side is usually covered by a haze of volatiles (mainly water vapor and carbon dioxide), which return to the ground as frost over the course of the long, cold night.

The Sirta Foundation has established a research outpost on Chohe to investigate the native subterranean life of Chohe, which shows incredible resilience to extremes of heat and cold.
