Chevallier is a lunar impact crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact crater ...

The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width ...
's near side, about a crater diameter east-southeast of the prominent crater Atlas
An atlas is a collection of maps; it is typically a bundle of maps of Earth or of a region of Earth.
Atlases have traditionally been bound into book form, but today many atlases are in multimedia formats. In addition to presenting geograp ...
. To the south-southeast of Chevallier is the flooded crater Shuckburgh.
This formation is little more than a disintegrated crater rim protruding upward slightly from a lava
Lava is molten or partially molten rock ( magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or ...
-flooded surface. All that survives of this feature is a few arcing sections of low ridges in the surface. The most prominent section of rim is along the northeast where it has merged with a smaller double-crater formation which has also been flooded. The interior floor has been resurfaced by the flows of lava, which are joined to the nearby flooded terrain. In the eastern half of the floor is Chevallier B, a small, partly flooded crater.
Just to the west of the rim of Chevallier is Atlas A, a sharp-rimmed, bowl-shaped crater.
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 Chevallier.See also
