Toutatis - LouisB3/Grannus-Expansion-Pack GitHub Wiki
Description
The second largest of the inner rocky planets, Toutatis looks like it might be an interesting place to visit. It is a fire and ice world, with one side forever baked by the heat of its sun, and the other shrouded in cold darkness. Between these extremes could lie a comfort zone, though the thin atmosphere isn't likely to afford much protection.
