Lalande is a small impact crater on the eastern edge of the Mare Insularum in the center of the visible moon side. The crater is surrounded by an area of ejecta with a high albedo . This runs out into a beam system with a maximum diameter of almost 300 kilometers .
The inner walls are terraced and there is a small elevation in the center of the crater floor. Lalande is believed to have originated around 2.8 billion years ago.
