Mare Moscoviense (Moon)

"Sea of Muscovy"

Mare Moscoviense is a lunar mare that sits in the Moscoviense basin. It is one of the very few maria on the far side. Like Mare Marginis, this mare appears to be fairly thin. However, it is clearly centered within a large impact basin. (wikipedia entry)

A mare is a "sea" or large circular plain. On the Moon they are named after latin terms describing weather and other abstract concepts.
