A multi-ringed basin (also a multi-ring impact basin) is not a simple bowl-shaped crater, or a peak ring crater, but one containing multiple concentric topographic rings;[1] a multi-ringed basin could be described as a massive impact crater, surrounded by circular chains of mountains[2] resembling rings on a bull's-eye. A multi-ringed basin may have an area of many thousands of square kilometres.[3]
An impact crater of diameter bigger than about 180 miles (290 km) is referred to as a basin.[4]
