Lucretius (crater)
Encyclopedia
Lucretius is an impact crater
on the far side of the Moon
. It is located to the southeast of the huge walled plain Hertzsprung
, within the outer skirt of ejecta that surrounds that impact feature. To the southwest of Lucretius lies Fridman
.
This crater is a relatively fresh impact, as the formation is well-defined and the rim and interior remain nearly unscathed from impact erosion. The rim has an outward bulge along the western side, so that it is slightly wider in longitude than latitude. The inner walls display some terrace structures, and the interior floor is somewhat uneven in places.
To the northwest of Lucretius is a chain of craters called the Catena Lucretius. These extend for a distance of 271 km across the southern floor of Hertzsprung, and include a number of craters ranging up to 15–20 km in diameter.
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...

Hertzsprung (crater)
Hertzsprung is an enormous lunar crater that is located on the far side of the Moon, beyond the western limb. In dimension, this formation is larger than several of the lunar mare areas on the near side. It lies in the northwestern fringe of the blast radius of the Mare Orientale impact basin...

Fridman (crater)
Fridman is the remains of a lunar crater on the far side of the Moon. It lies due south of the huge walled plain Hertzsprung, and is attached to the northeastern rim of the crater Ioffe....
