Cannon is a lunar crater that is located near the east-northeastern limb of the Moon's near side. It lies just to the northwest of the Mare Marginis, and south-southeast of the crater Plutarch. Farther to the east-northeast is Hubble.
This is a worn and eroded formation with an interior floor that has been resurfaced by lava. A small crater overlies the north rim, which forms a notch in the side. Tiny craters also lie across the rim northeast and at the southern edge. The interior is level and nearly featureless, with only a few tiny scattered craterlets to mark the surface. This floor has the same albedo as the surrounding terrain.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Cannon.
