Posidonius crater. The moon satellite

The lunar crater Posidonius is located in the Mare Serenitatis or Sea of ​​Serenity. It has a diameter of 95 kilometers and a maximum depth of 2.3 kilometers. Its relatively low depth is due to the subsoil of the Posidonius crater was saturated by ascending lava, which was pushing upwards until it fractured its soil.

The name of the crater, Posidonius, was awarded in honor of Posidonio de Apamea, an important Greek geographer and polymath of the second century BC. Polymata was known to that person who knew many things, what today we call scholar or "Man of the Renaissance."

The Posidonius crater has several peculiarities, which give it a very special and attractive appearance. For example, in the center of the same crater there is another small crater of 11 kilometers in diameter, called Posidonius A. Next to it is another even smaller crater, called Posidonius C, in addition to several elevations of the terrain that resemble the hills . The rest of the Posidonius crater is furrowed by gigantic cracks.

Posidonius is practically circular. Around it we can see another series of craters, such as the Daniell crater, the Chacornac crater or the Luther crater, under which a spectacular fold line called Dorsa Smirnov extends.

Through the middle of the crater a narrow and elongated shadow can be seen, caused by one of the central peaks of the column-shaped Posidonius.
