"Space junk" refers to any man-made objects or debris that are floating around in space. These objects can include old satellites, discarded rocket stages, or even fragments from collisions or explosions.
Space junk poses a risk to functioning satellites and space missions as they can collide with these objects, causing damage or destruction.
