Yes, space junk is real. It consists of defunct satellites, spent rocket stages, and other debris left in orbit around Earth. This space debris poses a risk to active satellites and spacecraft in orbit.
Space junk was first discovered in 1957 by the U.S. military tracking systems. The Soviet Union launched Sputnik 1, the first artificial satellite, which left debris in orbit around Earth, leading to the realization of space junk.
Space junk comes from defunct satellites, spent rocket stages, and debris from spacecraft collisions or explosions. Over time, these objects break apart and create smaller fragments that continue to orbit Earth. The accumulation of space junk poses a threat to operational satellites and space missions in Earth's orbit.
Space junk can remain in Earth's orbit for many years, ranging from decades to hundreds of years, depending on its altitude and the density of the Earth's atmosphere at that level. Some larger pieces may even stay in orbit for thousands of years.
Space junk travels as fast as all material that orbits the Earth or at about 17,500 miles per hour. This is fast enough to do damage to anything the junk encounters in orbit.

No. Space junk consists of fragments of spacecraft left in space. Saturn is a planet.

Satellites and space 'junk'.
If space junk means man-made objects, very few have left Earth-orbit. Of the ones in Earth-orbit many crash each year but the vast majority burn up because of friction as they come at high speed through the upper atmosphere.
It usually stays in orbit around the earth, and poses a serious threat to all orbiting satellites. Even a small object can destroy things at high speed. Most satellites can move around projected paths of junk thrown in space. Some astronomers use radio telescopes to track "Space Junk".
In a sense. In space, technically no object floats, but rather is in continuous free fall. Contrary to popular belief there is gravity in space; it is the may force acting on objects. Most space junk is in orbit around Earth, meaning that, while Earth's gravity continuously pulls it down, it is moving so fast laterally that it never hits the ground.
A projectile that falls around the Earth is in orbit. It is continuously falling towards the Earth due to gravity, but its forward velocity allows it to stay in a curved path around the planet without hitting the ground.
The orbit of "space junk" could deteriorate, resulting in the junk falling to earth. If the item survives re-entry and reaches the earth's surface, it would cause the same damage as an equally sized meteorite, including damaging or destroying structures in the area, killing people, etc.
