Moon

The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

. To the north is the smaller crater Alfraganus

Alfraganus (crater)

Alfraganus is a small lunar impact crater that lies in the rugged highland region to the southwest of the Mare Tranquillitatis. Northwest of Alfraganus is the crater Delambre, and to the south is the irregular Zöllner. The rim of Alfraganus is circular and retains a sharp edge that has not received...

. Southeast of Zöllner is the smaller crater Kant

Kant (crater)

Kant is a small lunar impact crater that is located to the northwest of the prominent crater Cyrillus and the comparably sized Ibn Rushd. To the northwest is Zöllner, and to the east is Mons Penck.
