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...

. It lies across the larger and more heavily worn crater Goldschmidt
Goldschmidt (crater)
Goldschmidt is a large lunar crater of the variety commonly termed a walled plain. It lies in the northern part of the Moon's near side, and appears oval in shape due to foreshortening. The rim is actually relatively circular, although the western rim is overlain by the prominent crater Anaxagoras...

. To the south-southeast is Epigenes
Epigenes (crater)
Epigenes is a lunar crater that is located in the north part of the Moon, and is sufficiently close to the northern limb to appear significantly foreshortened from the Earth. It lies just to the northwest of the remains of the walled plain W. Bond. Due north of Epigenes is Goldschmidt, and the...

Anaxagoras is a relatively recent impact crater that is young enough to still possess a ray system
Ray system
A ray system comprises radial streaks of fine ejecta thrown out during the formation of an impact crater, looking a bit like many thin spokes coming from the hub of a wheel. The rays can extend for lengths up to several times the diameter of their originating crater, and are often accompanied by...

Plato (crater)
Plato is the lava-filled remains of a lunar impact crater on the moon. It is located on the northeastern shore of the Mare Imbrium, at the western extremity of the Montes Alpes mountain range. In the mare to the south are several rises collectively named the Montes Teneriffe. To the north lies the...

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 Anaxagoras.
