Agatharchides (crater)
Encyclopedia
Agatharchides is a lunar
crater
located at the southern edge of Oceanus Procellarum
, in the region between the Mare Humorum
and Mare Nubium
. To the east-southeast is the crater Bullialdus
, and to the south-southwest lies Loewy
. It is named after the Greek
geographer
Agatharchides
.
The interior of the crater has been inundated by lava
in the past, resurfacing the floor. The damaged outer wall varies considerably in height, ranging from level with the surface to rising as high as 1.5 km. The most intact portions of the wall are along the east and the west-southwest, while the rim is nearly non-existent to the north and heavily damaged to the south. A small craterlet lies along the western rim. The interior floor is marked only by a few tiny craterlets.
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...

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...

Mare Nubium
Mare Nubium is a lunar mare in the Nubium basin on the Moon's near side. The mare is located just to the southeast of Oceanus Procellarum. The actual basin is believed to be of Pre-Nectarian system, with the surrounding basin material being of the Lower Imbrian epoch. The mare material is of the...

Loewy (crater)
Loewy is a small lunar crater that lies along the eastern rim of Mare Humorum, in the southwest part of the Moon's near side. This is a lava-flooded formation that lies to the southwest of the larger, lava-flooded crater Agatharchides...

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...
