Infinite Space Exploration

Alien Sun is what an exploration-focused space sim should be: The goal is just to explore someplace so far away that none of us will ever have the chance to see with our own eyes. Everything here is grounded in reality. Distances are approximately accurate, graphics are based on real-world physics where possible, and names are definitely plausible. So sit back and explore a beautiful real-time simulation of the 99.9% of the universe you and I could never see.
