In recent weeks there seems to have been a focus on role-play concerning space. I think it might be worth agreeing some of the details of what we believe to be out there. Personally I don't think we should feel constrained to perfectly replicate the real world (for example, I remember reading somewhere on the wiki that Terra was supposed to have two moons, although this may have been nonsense).
While I am not an astrophysicist, I do understand there are some constraints on what would be realistic for a planet of a similar size and climate to Earth so this would need to be considered too. With all that in mind: two questions for players. What has been done to your knowledge in terms of role-play related to space? Do you think anything should be changed or agreed as canon?
