Persophone 1

Persephone One is, as far as space rocks go, hospitable. It has an atmosphere and magnetosphere to keep the local fauna alive, it supports a native ecosystem, and it has liquid water. Of course the extremely high gravity and toxic atmosphere might be off-putting to any human colonists, but the local wildlife, universally brawny and tough thanks to the local gravity, has no complaints.

Persephone One has a resource score of 2/1.
