Description
editManilius has a well-defined rim with a sloping inner surface that runs directly down to the ring-shaped mound of scree along the base, and a small outer rampart. The small crater interior has a higher albedo than the surroundings, and it appears bright when the sun is overhead. Within the crater is a central peak formation near the midpoint.
The crater also possesses a ray system that extends for a distance of over 300 kilometers. Despite the presence of these rays, which generally indicate the age of the crater as Copernican, the crater is currently mapped as Eratosthenian age.[2][3]
Names
editManilius is named after the Roman astronomer Marcus Manilius.[1] Like many of the craters on the Moon's near side, it was given its name by Giovanni Riccioli, whose 1651 nomenclature system has become standardized.[4] Earlier lunar cartographers had given the feature different names. Michael van Langren's 1645 map calls it "Isabellae Reg. Hisp." (Isabella, Queen of Spain),[5] and Johannes Hevelius called it "Insula Besbicus" after the island in Turkey now known as İmralı.[6]
Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Manilius.
