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...

Galen (crater)

Galen is a small lunar impact crater that lies in the rugged region between the Montes Apenninus range to the west and the Montes Haemus in the east. It is located to the south-southeast of the crater Aratus, a slightly larger formation. Further to the west is the crater Conon, near the flanks of...

Aratus (crater)

Aratus is a small lunar impact crater located on the highland to the south and east of the rugged Montes Apenninus range. It is a circular, cup-shaped crater with a relatively high albedo. To the east is the Mare Serenitatis, and to the southwest is the somewhat larger crater Conon...

, about the same distance to the northeast.

The edge of Conon's rim is sharply defined and has not received significant erosion from later impacts. The inner wall is somewhat variable in width, and the interior floor forms an irregular oval shape. This irregularity may be due to the rough and uneven surface on which the crater was formed. The floor is rough, but lacks a central prominence of note.

The crater is named for the astronomer Conon of Alexandria (fl. 250 BCE).

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 Conon.
