Universe - The Stock Interstellar Experience
Universe removes the stock system and replaces it with 28 new planets and moons in orbit around four stars.
However, to keep these planets accessible in the stock game, without resorting to high-tech mods, the universe is scaled down to 1/10 Kerbal scale.
This mod requires Kopernicus, which can be found HERE.
