If you desire to explore the stars but don't have time to waste training with NASA, then these PC space games for Steam are the next best thing. There are plenty of cool PC space games available on Steam, but instead of wasting time in the Steam store, check out these recommendations which have been ranked by gamers like you. All of these PC games take place in space, whether it's a space station, foreign planets, or even the moon.

Want to stay on earth, but help someone else get to the moon? Try the rocket building space game, Kerbal Space Program. Is destruction on unimaginable scale more your speed? There's the physics based sandbox space game, Universe Sandbox ², which lets you smash galaxies together just to see what would happen. If those don't sound good, then xxplore an infinite number of galaxies in a procedurally generated space game like No Man's Sky or Starbound.

There's a never ending expanse of space games on Steam. Vote on the games below to find out which PC space game is the best in the galaxy.  If there are any that are not on this list, go ahead and add your favorite Steam space video games at the bottom.
