Around each planet there is a gravitational field, thanks to which objects can rotate around the planet in different orbits. Today in the game Planet Gravity you will launch artificial satellites around one of the planets using its gravitational field. A satellite will appear on the screen in front of you, which will be at a certain height above the planet. You click on it to call a special line. Thanks to it, you can calculate the orbit in which the satellite will rotate. Once you're ready, launch it. If everything goes well, then the satellite will rotate around the planet, and you will proceed to launch the next one.
