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...

Mare Crisium

Mare Crisium is a lunar mare located in the Moon's Crisium basin, just northeast of Mare Tranquillitatis. This basin is of the Pre-Imbrian period, 4.55 to 3.85 billion years ago. This mare is in diameter, and 176,000 km2 in area. It has a very flat floor, with a ring of wrinkled ridges...

Tralles (crater)

Tralles is an irregular lunar crater that is attached to the northwestern rim of the much larger crater Cleomedes, in the northeastern part of the Moon. Within one crater diameter to the northwest is Debes....

Cleomedes (crater)

Cleomedes is a prominent lunar crater located in the northeast part of the visible Moon, to the north of Mare Crisium. It is surrounded by rough ground with multiple crater impacts. The irregular crater Tralles intrudes into the northwest rim. To the east is Delmotte...

.

This crater is joined to the oval-shaped Debes A through a break in the southern rim. The later crater is joined along its western rim by Debes B, so that the result is a triple-crater formation. The surviving of Debes is somewhat eroded and rounded, when compared to the sharper-rimmed Tralles, and the interior floor is relatively level and featureless.

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 Debes.
