Nodens - LouisB3/Grannus-Expansion-Pack GitHub Wiki
Description
Nodens is a large terrestrial planet right smack in the middle of its star's Goldilocks zone. Likely having a thick atmosphere, and possibly liquid water on its surface, Nodens could be an ideal habitat for life. But just how commonplace is life? Will we find a world teeming with flora and fauna, or will it disappoint by being bleak and lifeless? This gem is undoubtedly near the top of any list of places to visit.
If GEP_Primary is installed:
Nodens is a large terrestrial planet with a thick warm atmosphere and expansive oceans. It is the ideal habitat for life, and home world of the Kerbals. While Kerbals are industrially and technologically advanced, they make every effort to ensure that the ecological balance of their world is not disturbed. Much of the planet remains an untouched wilderness.
