The United States’ National Aeronautics and Space Administration (NASA), is sending a mission called DART to collide with a small asteroid orbiting a larger one to see if it can knock it off its course by impact alone.
The rock is about 41 metres in diameter and orbits the Sun but remains close to Earth. It may have been the result of a collision striking the Moon, based on the light it reflects.
The global space race comes at a cost, as exploration missions, anti-satellite missile tests and accidental collisions continue to add to the millions of pieces of trash already orbiting the Earth.
The rock, named 4660 Nereus, will pass Earth at a distance 3.9 million kilometres on 11 December.

In a celestial phenomenon not seen in 397 years, Jupiter and Saturn, from the perspective of observers on Earth, align closely in an intimacy that will not occur again until 2080.
NASA has discovered molecular water on the lunar surface, trapped within natural glasses or between debris grains. Water is a precious resource and a relatively plentiful lunar presence could prove important to future astronaut and robotic missions.
Known as NWA 12691, it is thought to be the fifth largest piece of the moon ever found on Earth. There is just 650 kg of moon rock known to be on Earth.
