Do you ever wonder why satellites don't fall to earth? It's because they're in, what is officially known as an orbit. An orbit is a very special combination of height and speed, that if chosen properly, will keep a satellite in a stable, predictable, path around the earth, without ever crashing.

This selection allows you to experiment with your own values of height and speed, to see if you can successfully put your own satellite in orbit around the earth. Good luck!
