Sinas (crater)

Sinas is a small lunar impact crater that lies in the eastern part of the Moon on the Mare Tranquillitatis. Its diameter is 12 km. It was named after the Greek magnate Simon Sinas. This is an isolated formation that is located very near the midpoint of the lunar mare. Sinas is circular and bowl-shaped, with a small floor at the midpoint. A wrinkle ridge intersects the east edge of the crater, and several lunar domes lie to the north.
