Drebbel (crater)
Encyclopedia
Drebbel is a small lunar
crater
that is located to the northeast of the large walled plain Schickard
, in the southwestern part of the Moon
. Further to the northeast is the Lacus Excellentiae
and the small crater Clausius
.
The rim of this crater is roughly circular, with an outward bulge along the east and southeast side. Along this arc of the inner wall is s single terrace where the material has slumped downwards. The west and northwest sides have accumulations along the base where loose material has slumped to the floor. The remainder of the inner rim is a simple slope that runs down to the interior floor. The rim is relatively sharp-edged and not noticeably worn. There is a level interior floor that is just over half the crater diameter.
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...

Schickard (crater)
Schickard is a lunar impact crater of the form called a walled plain. It lies in the southwest sector of the Moon, near the lunar limb. As a result the crater appears oblong due to foreshortening. Attached to the northern rim is the lesser crater Lehmann, and to the northeast is the even smaller...

Lacus Excellentiae
Lacus Excellentiae is a relatively small, irregular lunar mare in the southern latitudes of the Moon, amidst the rugged terrain to the south of the larger Mare Humorum. The most prominent feature within the diameter of this basin is the small crater Clausius.The selenographic coordinates of this...

Clausius (crater)
Clausius is a lunar crater that is located in the southwest part of the Moon, in the small lunar mare designated Lacus Excellentiae. It is completely enclosed by mare material, although the tiny satellite crater Clausius A lies just to the north. The rim of Clausius is low and sharp, with a...
