Hipros is the lightest known celestial in the whole PE31 system. Orbiting relatively far away from the parent planet, Fippa, it rotates sluggishly around its' axis.
It has a thick, methane-based atmosphere with sulfuric clouds, causing and reinforcing a runaway greenhouse effect. Mean surface temperature is moderated by the lenghty distance from both Fippa and the PE31 star.
The nature of green and brown features on the surface of Hipros is yet to be confirmed, but for now it is believed that these are the microbes (lifeforms that in this case are not necessarily carbon-based), that formed a moon-wide thriving colony. Potentially, the Hipros' atmosphere is yet another of their creations that impacted the moon as a whole...
