Spacejunk is a computer game about traveling in 2D planetary systems. The player must collect drifting garbage by navigating through the gravitational fields of planets and stars. A rough editor for planetary systems is provided too.

Check the Spacejunk manual to learn how to play. You can read about the making of Spacejunk to know where it came from.

Earth is surrounded by 600 thousand of human-made debris. Some of them are big, some of them are the size of a hand, and most of them are smaller than a fingernail.

Thousands of little plates, nuts, bolts and even gloves become a serious threat to any passing spacecraft when traveling at orbital speeds (around 25000 or 30000 km/h).

How hard can be cleaning the space?
