Just found a near perfect colonisation prospect: . 95 G, 70% N, 28. 8% O, 1. 2% Argon atmosphere at 0. 77 atmospheric pressure. Sure, it's tidally locked and it has no hydrosphere, but that has no mechanical effect on the planet whatsoever. Unfortunately, there is a reason why it's only near perfect.
The planetary temperature is balmy -132 degrees centigrade.
