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...

Impact crater

In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

Mersenius (crater)

Mersenius is a lunar crater that is located to the west of the Mare Humorum, in the southwestern part of the Moon. To the southwest is the crater Cavendish, and to the south-southeast lies Liebig. Mersenius is 84 kilometers in diameter and 2.3 kilometers deep...

Mare Humorum

Mare Humorum is a lunar mare. The impact basin it is located in is 825 kilometers across. It was not sampled by the Apollo program, so a precise age has not been determined. However, geological mapping indicates that it is intermediate in age between the Imbrium and Nectaris Basins, suggesting an...

De Gasparis (crater)

de Gasparis is a lunar crater that is located in the southwest part of the Moon. It lies to the southwest of the crater Cavendish and south of Mersenius.The rim of de Gasparis is worn and eroded, and the interior has been flooded by basaltic lava...

.

The rim of Liebig has a low inner wall, with an interior floor that is nearly featureless except for a few tiny craterlets. It is nearly, but not quite circular, with outward bulges to the west and southeast. The small, cup-shaped crater Liebig A lies along the inner wall and part of the interior floor.

The western edge of the Mare Humorum is a fault line designated the Rupes Liebig, named after this crater. This fault extends for about 180 km along the shore. To the southwest, in the section of lava

Lava

Lava refers both to molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling. This molten rock is formed in the interior of some planets, including Earth, and some of their satellites. When first erupted from a volcanic vent, lava is a liquid at...

Rille is typically used to describe any of the long, narrow depressions in the lunar surface that resemble channels. Typically a rille can be up to several kilometers wide and hundreds of kilometers in length...

s named the Rimae de Gasparis. These cover an area with a diameter of 130 km.

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 Liebig.
