Larmor is a lunar crater on the Moon's far side. It is located to the east-southeast of Shayn crater, and due north of Dante crater, in honor of the physicist Joseph Larmor.
The rim of Larmor is broken across by the satellite crater 'Larmor Z'. The remaining rim is slightly worn, particularly to the southwest, and the inner wall is somewhat wider at the southern end. The wider southern inner wall displays terrace structures. Near the mid-point of the otherwise relatively level interior floor are some low hill features.
The satellite crater 'Larmor Q', located about one and a half crater diameters to the southwest of Larmor crater, lies at the center of a ray system. These rays lie primarily within cones to the north and southeast, which a 120° arc to the west is free of ray material.
[edit] Satellite craters
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 Larmor crater.
