Manners is a lunarimpact crater located in the western part of the Mare Tranquillitatis. Its diameter is 15 km. It was named after British astronomer Russell Henry Manners.[1] To the northeast is the larger crater Arago and to the south are Ritter and Sabine. The crater has a rim with a higher albedo than the surrounding mare, making it appear bright. This is a circular, bowl-shaped feature with a raised rim and a relatively flat interior.

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