Wargo Crater is an 8.6-mile (13.8 km) diameter impact crater sitting on the northwest edge of Joule T crater, on the far side of the Moon.

The formation of Wargo crater had a big impact on its surroundings. An asteroid measuring several thousand feet in diameter slammed into the steeply sloping rim of Joule T crater (24 miles or 38 km in diameter) at hyper-velocity (3 to 12 miles per second) forming a crater over 3,000 feet (914 meters) deep. Massive amounts of instant magma crested the lower eastern rim and spread across the floor of Joule T.
