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...

Abbe is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon. It is located just to the south of the crater Hess, and lies to the east of the large walled basin Poincaré. It is named after the German physicist Ernst Abbe.The outer wall of Abbe is somewhat...

 to the west. The region about this crater is relatively level, although marked with a number of fresh, bowl-shaped craters.

The form of Haret is generally circular, with an outward notched in the southwest rim where a smaller crater has merged with the formation. There is a second, even smaller impact in the northeast rim. The interior floor has been flooded in the past by basalt

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 Haret.
