Lalande is a small lunar impact crater that lies in the central part of the visible Moon, on the eastern edge of Mare Insularum.
[1] The crater is surrounded by a high-albedo area of ejecta that extends into a ray system with a maximum radius of over 300 kilometers.
The interior wall has a terrace system, and there is a small central rise at the midpoint of the floor.
Its young age is indicated by the bright rays of ejecta surrounding the crater, its sharp features, and the relative lack of later impacts in its interior.
[4] By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Lalande.
