Watt (crater)
Watt is a lunar impact crater that lies near the eastern limb of the Moon. It is located to the south of the Mare Fecunditatis, and northwest of the Mare Australe. To the southwest of Watt is the prominent crater Steinheil, and to the north is the smaller Borda. Due to its location, Watt is viewed at a low angle from the Earth, which limits the amount of detail that can be observed.
The outer rim of Watt is heavily eroded and indented, giving it a somewhat irregular appearance. The satellite crater Watt A intrudes slightly into the northeastern rim. A number of smaller craters lie along the rim edge and the inner walls. The interior floor is relatively level, and marked only by several tiny craterlets.
Watt is named after the Scottish inventor James Watt.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Watt.
