- Sheep (Wikipedia)
Sheep or domestic sheep (Ovis aries) are domesticated, ruminant mammals typically kept as livestock. Although the term sheep can apply to other species in the genus Ovis, in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ewe (/juː/), an intact male as a ram, occasionally a tup, a castrated male as a wether, and a young sheep as a lamb.
- Langrenus (crater) (Wikipedia)
Langrenus is an impact crater located near the eastern lunar limb. The feature is circular in shape, but appears oblong due to foreshortening. It lies on the eastern shore of the Mare Fecunditatis. To the south is the overlapping crater pair Vendelinus and the smaller Lamé.
