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...

Euctemon is a lunar crater that is located in the northern part of the Moon, along the northwest rim of the crater Baillaud. To the southwest of Euctemon is the large walled plain Meton, and to the north-northeast lies the crater De Sitter...

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...

-flooded surface to the south.

The interior of Baillaud has been submerged by past lava flows, leaving a flat surface that is marked only by many tiny craterlets and the satellite crater Baillaud E in the western half. The crater interior lacks a central peak or significant ridges.

Nearby craters include the irregular Meton

Meton (crater)

Meton is a compound formation on the Moon that consists of several merged crater rings that have been flooded with lava, forming the remnant of a walled plain in the shape of a clover leaf. It is located near the northern lunar lumb, and is viewed from a low angle and foreshortened. The crater...
