Comrie is a
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 ...

Parenago to the northeast.
This feature forms the central member of a formation of three connected craters. A slightly smaller crater is attached to the northern end, and the two share a straight rim. This crater also lies across the northern part of a larger, heavily worn feature to the south, and little of Comrie's rim survives along its southern extent. The remaining rim is worn and eroded.
Within the crater interior, a small crater lies near the northwest rim, a smaller crater just to the southwest of the midpoint, and a still smaller crater along the surviving southwest rim. There is a low central ridge at the midpoint. The eastern half of the interior floor is somewhat irregular, but contains only a few tiny craterlets. Streaks from the

A ray system comprises radial streaks of fine ''ejecta'' thrown out during the formation of an impact crater, looking somewhat like many thin spokes coming from the hub of a wheel. The rays may extend for lengths up to several times the diameter ...

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 Comrie.
