It is located to the south of the much larger crater Fowler, and to the west of Klute.

This crater, like many features on the Moon, has an eroded outer rim that has been modified by subsequent impacts.

Gadomski in turn overlies the western portion of a still larger, and unnamed crater feature that is even more heavily eroded.

The interior floor is relatively featureless, with a few tiny craterlets marking the surface.

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