Scaliger is a prominent
lunar impact crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact crater ...

The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width ...
. It is attached to the northwest rim of the walled plain
Milne, and the shared perimeter has reshaped the outer wall of Scaliger slightly, producing a straightened section along the southeast. To the west of Scaliger is the
Lacus Solitudinis.

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