Oblique view fromApollo 10, with Ariadaeus in lower left and Rima Ariadaeus extending to the horizon
Ariadaeus is a small, bowl-shapedlunarimpact crater on the western shores ofMare Tranquillitatis. It lies to the north of the craterDionysius, and to the west-southwest ofArago. The crater is joined along the northeast rim by the slightly smaller Ariadaeus A, and the two form a double-crater. Its diameter is 10.4 km.[1]
This crater marks the eastern extent of therille designatedRima Ariadaeus. This wide rille extends in a nearly straight line to the west-northwest, passing just to the north of the craterSilberschlag. Other rille systems lie in the vicinity, including the Rimae Ritter to the southeast and Rimae Sosigenes to the northeast.
