So how far into the future are we? Has humanity gone beyond Sol? Earth still around?(I ask because a friend is interested in playing as Earth in such a setting, also to be a the opposite of my faction, of which I'll present below)

My faction is a Sentient Planet. Both leader and Homeworld of a race of Space Bugs that function as weapons of it's will. After wiping out it's previous native population in a long war. The planet has grown slowly insane over time. Now it feels that it must now cleanse the galaxy of civilization and technology.

What do you think?
