The asteroid was initially spotted by amateur astronomer Gennadiy Borisov on Saturday and reported to the Minor Planet Center (MPC)
The mission is NASA's first demonstration of the agency's planetary-defense initiative to protect Earth from the possibility of a hazardous collision with an asteroid
Dimorphos doesn't pose any threat to Earth, but the DART mission is the first physical test in space of one of NASA's primary tenets: planetary defense.
Nasa estimates the asteroid's relative speed at around 8.16 kilometres per second
NASA's Near-Earth Object (NEO) web-site at the Centre for Near Earth Object Studies (CNEOS) reveals that they will be fast approaching the Earth this month
The reason for this jump in the impact rate is not known but it could be related to large collisions taking place more than 290 million years ago
