Vallis Rheita
From Wikipedia, the free encyclopedia
Vallis Rheita is a linear valley on the near side of the Earth's moon. It is located in the southeastern quadrant, and is oriented radially to Mare Nectaris. 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 , and it has a diameter 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 Rheita crater, for which this formation was named. Further to the southeast is Young crater, nearly centered across the valley. Next to Young is 'Young D', also laying across the valley but less distorted by the rift.
Further southeast are the Mallet and Reimarus craters, the later located near the difficult-to-discern terminus. The satellite crater 'Mallet D', next to Mallet, also overlays part of the valley.
