Rima Ariadaeus is a linear rille on the lunar surface, situated at coordinates 6°24′N 14°00′E / 6.4°N 14.0°E. Measuring approximately 5 km (3.1 mi) in width and spanning a length of 300 km (186.4 mi), it stretches between Mare Tranquillitatis and Mare Vaporum.[1][2]
Experts agree that Rima Ariadaeus, about 300 km (186.4 mi) long, is a fault system similar to those on Earth.
