Space debris, man-made space pollution
Space debris, also known as space debris or space junk, is the remains of man-made devices and satellites orbiting the planets in the solar system.
Most of this space debris revolves around the planet Earth in the solar system. It includes everything that is no longer needed in space, such as a damaged satellite or parts of space rockets. This space debris can consist of small to large pieces of bile, such as paint pieces from spacecraft.
Gradually, space debris is gaining the attention of space research institutes such as NASA, as it could be dangerous for satellites and spacecraft.
This is because most of the space debris is orbiting the earth at a dangerous speed of 8 km per second (about 28800 km per hour). At this speed, these space debris, no matter how small, is enough to make holes in the structures of spacecraft and satellites, but they can also endanger the lives of astronauts.
A body the size of a tennis ball orbiting at this speed has the potential to wreak havoc equal to 25 dynamite, while it is estimated that a colliding force equal to a pea-sized body rotating at this speed has a collision force of 100 km. At a speed of (60 miles) can weigh the equivalent of 181 kilograms, which is certainly very dangerous.
There are an estimated 5.5 million kilograms of space debris in the Earth's orbit, with approximately one million bodies larger than one millimeter, 300,000 bodies larger than one centimeter, and 13,000 bodies larger than tennis balls.
NASA estimates that if space debris reduction guidelines are not followed, space debris in the Earth's lower orbit will increase by 75% over the next 200 years.
