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...

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...

Eötvös is the remains of a lunar crater on the far side of the Moon. It lies to the north-northwest of the walled plain Roche, and east-southeast of the equally ruined Bolyai....

Rosseland (crater)

Rosseland is a lunar impact crater on the far side of the Moon. It lies less than one crater diameter to the northeast of Carver, and about the same distance to the west of the larger Roche. To the northwest lies the smaller Coblentz....

.

The western rim of Roche has been somewhat distorted and straightened. The rim as a whole is worn and eroded, with multiple tiny craterlets marking the surface. The satellite crater Roche B lies across the northeastern inner wall.

The interior floor of Roche is relatively level, but is also marked by several small and tiny craterlets. A grouping of these craters lies near the mid-point. Just to the northwest of this grouping is a bright patch of high-albedo

Albedo , or reflection coefficient, is the diffuse reflectivity or reflecting power of a surface. It is defined as the ratio of reflected radiation from the surface to incident radiation upon it...

Basalt

Basalt is a common extrusive volcanic rock. It is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet. It may be porphyritic containing larger crystals in a fine matrix, or vesicular, or frothy scoria. Unweathered basalt is black or grey...

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...

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 Roche.
