The ninth planet in the UX-11 System is habitable but currently only holds microbial life. It can be very cold on the surface.

Because of high obliquity (exceeding the 54° threshold), the equator is cooler, on average, than the poles of the planet and the changing of the seasons brings extreme climate change.
