I figured you'd have problems with traction or staying glued on the surface in a low gravity world. Would this be... (more)	—	over 5 years ago

At first I wanted the planet to have either no atmosphere or a very thin one. But I want this to be as close to realistic as possible. So, would a planet be guaranteed to have a thick atmosphere with a gravity well that... (more)	—	over 5 years ago
