Vega (76 km) is an eroded lunar crater and can be seen from Earth even if is located at the Moon's terminal. Southeast of Vega is Peirescius a slightly smaller crater and to the west is the crater Reimarus and the long Vallis Rheita.
Vega crater which is 2.9 km deep, was bombarded and eroded by a long history of impacts. Vega B (30 km), overlaps the southern part of the floor. On the north-eastern edge overlapses with a pair of small craters. The rest of the floor has no features except a few small craters.
Crater name is given in honor of baron Jurij Bartolomej Vega (Georgius Bartholomaei Vecha)-March 23, 1754 - September 26, 1802, which was a mathematician, physicist and artillery officer.
Vallis Rheita is a linear valley situated south-east of the Moon, and is oriented to Mare Nectaris. This valley seems to share a common origin with Vallis Snellius which lies to the north-east, because both are orientated in the same direction.
Valley is 445 km long, and a width of about 30 km, but narrows to 10 km to the extreme southeast. It is the longest valley on the Moon, being exceeded only by Vallis Snellius.
Vallis Rheita was eroded by a series of impacts, and more notable craters are located along this valley. Near the end of the northwest is the crater Rheita, like this valley was also named. Further to the southeast is the crater Young (72 km), almost centered in the valley. Young D (46 km) is located near the valley, but less ,deformed.Further, to the southeast are craters Mallet (58 miles), and Reimarus (48 km). Satellite crater Mallet D (42 km), is also covering part of the valley.
