Aquerraris

Aquerraris, meaning water dirt and dark, is the sole moon of the planet Saleris. The moon rotates so slowly, it is essentially tidally locked to the star Calux. One side of the planet is a frozen wasteland that never sees the light of day. The temperatures range between -100°F (-73°C) and -250°F (157°C) on the perma-dark side. The side permanetly facing the sun, would always see light if it weren't for it orbiting around Saleris, eclipsing itself for several hours a day. The Calux side of the planet is nice comfortable 70°F (21°C) year round.

Days on Aquerraris are measured by how long it takes the moon to orbit its planet, taking 20 hours to complete a single lap. Dawn and dusk both take an hour each to complete the transition from light to dark and vise-versa with dusk occurring between hours 15 and 16, and dawn occurring between hours 20 and 1 (the beginning of a new day). Full night time occurs between the hours of 16 and 20 and would be pitch black if it weren't for several sources of natural and artificial illumination. Small light bursts of energized neon gases from its host planet creates a small shimmering sky light, while many plants and animals on the ground produce ambient lighting.
