Cassegrain (crater)
Encyclopedia
Cassegrain is a lunar
impact crater
that is located on the far side of the Moon
, beyond the southeastern limb. It lies to the southeast of the larger crater Lebedev
, and to the northeast of the comparably-sized Priestley
.
The interior of this crater has a relatively dark-hued floor, a feature it has in common with other craters to the west and northwest that form part of the Mare Australe
. The floor is level and mostly featureless, except for some deposits in the northwest corner. The rim is more heavily worn in the northwest corner than elsewhere, and the remaining inner wall displays a slumped shelf below the rim.
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...
