. 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

, and it has a length of 445 km. At its maximum extent this valley has a width of about 30 km, but it narrows to 10 km at the southeastern extreme. 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. Near the northwestern end is the crater Rheita, for which this formation was named. Further to the southeast is the crater
