The moon is about to get a visitor ... Three tons of space junk will be crashing into the moon with a punch that'll carve out a massive crater on Friday.

Initially, astronomers thought it was a piece of a SpaceX rocket that launched seven years ago and was abandoned in space after its mission was completed. Experts now believe the space junk is a leftover rocket booster from a launch in 2014 by China's space agency's lunar exploration program.

Officials in China, however, have denied it's theirs.

Regardless of who the space junk "belongs to," it's big enough to "carve out a hole 33 feet to 66 feet (10 to 20 meters) across and send moon dust flying hundreds of miles (kilometers) across the barren, pockmarked surface," writes The Associated Press.

The space junk will be crashing at 5,800 mph into the far side of the moon. Unfortunately, this means the impact will be away from our prying eyes. The confirmation of the impact could take weeks or even months, says AP.
