Astrophotography by Anthony Ayiomamitis

Lunar Image Gallery - Vallis Rheita

Named after the 17th Czech astronomer, this series of crater depressions in the southeastern quadrant measures 445 km in length and approximately 29 km in width. The initial section is bounded to the north by crater Rheita and crater Young further south where the valley then makes a dramatic shift towards the southwest and terminates at crater Mallet. As indicated by the image below, Rehita Valley is comprised of a series of craters which overlap each other. This area is believed to be approximately 3.92 billion years old and is considered to be a result of the Nectaris impact basin and the radial ejecta from it leading to various formations in this particular area including Vallis Snellius.

Note: See S&T (Jun/2004: 68-69) for further information in relation to Vallis Rheita.
