Eponym Mikhail K. Yangel'

Yangel' is a small lunar impact crater that is located in the irregular terrain to the north of the Mare Vaporum.

Just about 130 km west is the lunar Prime Meridian. Also the sun rises just before or after the third quarter of Earthshine and the sun sets just before its first quarter.

Description

Its diameter is about 8 km and its depth is around 400 meters. It is a relatively solitary crater formation, and the nearest larger craters lie more than 100 kilometers distant. To the southeast of Yangel' is the prominent crater Manilius. Conon is located to the northwest, near the flanks of the Montes Apenninus range.

LRO image featuring Yangel' and its rille

Just to the north of Yangel' is the small lunar mare named Lacus Felicitatis, or Lake of Happiness. To the northeast, forming a bay on the Mare Vaporum, is Sinus Fidei. A sinuous rille named Rima Conon runs along the middle of this feature, reaching the northern end and another named Rima Yangel', a wider one runs east-west south of the crater.

This is a circular, bowl-shaped crater with a narrow outer rim. The interior floor has a relatively low albedo that matches the dark hue of the mare to the south.

Naming

The crater and the rille (rima) are named after Mikhail Kuzmich Yangel'.[1] This crater was formerly designated Manilius F before being given a name in 1973 by the IAU.[1] The rille was named by the IAU in 1978.[1]
