Vallis Rheita

This valley appears to share a common origin with the Vallis Snellius to the northeast, as both are oriented radially with Mare Nectaris.

The center of the valley lies at selenographic coordinates 42°30′S 51°30′E / 42.5°S 51.5°E / -42.5; 51.5, and it has a length of 445 km.

It is the second longest such valley on the near side of the Moon, being exceeded only by Vallis Snellius.

Vallis Rheita has been eroded by a series of impacts, and several notable craters lie along the length of this valley.

Further southeast are the craters Mallet and Reimarus, the later located near the difficult-to-discern terminus.
