Rima Ariadaeus is a linear rille on the Moon at 6°24′N 14°00′E / 6.4°N 14.0°E / 6.4; 14.0. It is named after the crater Ariadaeus, which marks its eastern end. Over 300 kilometers long,[1] it is thought to have been formed when a section of the Moon's crust sank down between two parallel fault lines (making it a graben or fault trough). It is a relatively young lunar feature, with few craters or other features overlying it. The west end intersects with Rima Hyginus.


  1. ^ "Rima Ariadaeus, a Linear Rille". NASA. Retrieved 8 June 2016. Experts agree that Rima Ariadaeus, about 300 km (186.4 mi) long, is a fault system similar to those on Earth.
