Segers is a small lunar impact crater that is located on the Moon's far side.

Segers is unusual in that all of its satellite craters have a larger diameter.

The rim is not significantly worn due to impact erosion, and the edge remains sharp.

The inner wall has a relatively high albedo, giving the crater a bright appearance.

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