Satellites and space vehicles in orbit are in danger of being damaged.
Debris.
Space experts say there are more than 100 million pieces of space debris in Earth's orbit.
Many are large enough to possibly cause damage to satellites that operate in space, such as the International Space Station.
Debris is what remains after something has ended or been destroyed.
Debris can include small pieces of garbage or items that have been abandoned.
Space debris is human-made objects orbiting in space, but no longer serving the purpose.
