Move around using WASD (right/left and forward/backward) and R and F to go up/down. Mouse or arrow keys to pan the camera. Open the menu to adjust the settings and/or edit planets' orbits. H to go home, L to enable/disable locked mode, and G to go to the selected planet. O to enable/disable orbits. I to turn inertia on and off. Relative distances and paths are all to scale (except for moons) and 100% mathematically accurate.
If you look around at the stars you will find that you can see Orion, Cassiopeia, and other constellations that are real.
