|Eponym||Johann H. Schröter|
Schröter is a lunar impact crater near the mid-part of the Moon, on the eastern Mare Insularum, and named after German astronomer Johann Hieronymus Schröter. It lies to the north of the craters Sömmering and Mösting. To the southeast of the crater rim is a rille named the Rima Schröter. This cleft begins at a small crater in the mare, then follows a line to the south-southeast.
The rim of Schröter is heavily worn and eroded, with a wide gap in the southern wall and a deep indentation to the southeast. There is no central peak at the crater's midpoint. A widely spaced row of tiny craters forms a line westwards from the north rim of Schröter.
To the north of Schröter, beginning with the satellite crater Schröter W, is a region of irregular terrain. This area includes an array of linear dark surface markings that appear to criss-cross. In the 19th century, Franz von Gruithuisen is noted for claiming that this area contained a lunar city (which he called Wallwerk), based on his observations using a small refracting telescope. This inference was greeted with considerable skepticism by astronomers at the time, and, indeed, subsequent observations with more powerful instruments demonstrated that this was merely a natural feature.
About 100 km to the west-northwest of Schröter is the crash site of Surveyor 2.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Schröter. All of its satellite craters are located to the north and the west.
