Galios

MAIN INSPIRATION:
Dwarf planets like Pluto/Planet Grajani by ExcaliburAerospace.
LORE NOTE:
Galios is by far the largest moon of Seron, mostly comprised by silica rocks with some metal deposits under the surface. The planet has long ceased all volcanic activity having a weak magnetosphere and no atmosphere. This can be noticed by the almost absent mountains while craters are all over the surface, caused by meteor impacts in the past. The surface is covered in a greyish white dust forming some interesting patterns, aswell as by reddish patches that grew over time caused by complex organic molecules called tholins, which form when solar ultraviolet light and cosmic rays interact with methane, nitrogen, and other gases in Galios's now gone atmosphere and on its surface, creating a reddish "gunk" that settles down. These tholins build up over time, giving some regions their distinctive red hue, even though the exact chemical recipe is still being researched.
