Douglass (lunar crater)
Encyclopedia
Douglass is a lunar
crater
on the far side of the Moon
. It lies to the southwest of the crater Frost
and south-southwest of the large walled plain Landau
.
The western rim has been shaped by several interior impacts, most notably the remnant of a crater that cuts an outward notch in the northwestern rim. The southeastern rim of this interior crater is now little more than a low rise across the floor of Douglass. Another impact along the southern side has produced a smaller outward bulge and a portion of the rim forms a ridge prodruding into the interior floor. Smaller craters lie along the northeastern rim. The remainder of the rim is worn and rounded, and the interior floor is otherwise level and featureless.
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...
