It's a little disappointing, but still good. Arrow keys to shift the blue "planet" Click and drag the orange planets to move them Space to simulate fuel conditions and trajectory The gravity level slider adjusts the gravitational pull of the orange planets (set it to 20 to appreciate what NASA does for us) The number of planets. . .you get it
Inspired by https://scratch.mit.edu/projects/356305548/ This is a math and physics-heavy project and is completely realistic (minus how gigantic the planets are considering how far apart they are). The reason why the gravity seems to take a while to kick in is that IT REALLY DOES TAKE THAT LONG, EVEN WHEN PLANETS ARE THIS CLOSE TO ONE ANOTHER. If you want to know how it works, look inside. There are notes.
