Xenosphere

Xenosphere is a 2,440 km wide planet that orbits around the red dwarf star of Maldonar, Xenosphere is a tidally locked planet that is closest to the central star, the side of the planet facing the sun is mostly a scorched desert with a lot of canyons and mesas. The sun side region is so hot it is near uninhabitable without proper safety equipment, the area is always at 65°C.
The opposite side of Xenosphere is a heavily frozen scape with a temperature of -100°C.
Such low temperature of the region makes it heavily uninhabitable. The cold region is also stuck in eternal darkness.
The Twilight zone between the cold and hot region is easily survivable but requires survival equipment due to no oxygen being in the area as all animal and plant life are nonexistent on the planet.
