Cannonis alunarimpact craterthat is located near the east-northeastern limb of theMoon's near side. It lies just to the northwest of theMare Marginis,and south-southeast of the craterPlutarch.Farther to the east-northeast isHubble.
This is a worn and eroded formation with an interior floor that has been resurfaced bylava.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 samealbedoas the surrounding terrain.
The crater is named afterAnnie Jump Cannon,an astronomer who classified 300,000 stellar bodies.
