Left and right arrow keys to change the planet you're focused on. WASD for camera controls (Will unfocus you from anything you're focused on) Precision mode makes the calculations more precise by running all of them before updating the position. This can cause noticeable amounts of lag with only 45 bodies on screen
This is something I've been trying to make for years. Every planet calculates its position using the other planets, making it as realistic as possible. A cool thing is, it can run with legitimately any number of planets! The only cap is Scratch's clone limit
