Van Rhijn (crater)
Encyclopedia
van Rhijn is an old lunar
crater
that is located on the far side of the Moon
, in the northern hemisphere
. It lies due south of the larger crater Störmer
, and to the north-northeast of De Moraes
.
The outer rim of this crater has been deeply worn and eroded by impacts, with smaller craters intruding into the northeast, northwest, and southeastern parts of the rim. The remaining features of the rim have been softened and rounded, leaving the crater little more than a depression in the surface. The interior floor is relatively flat and featureless, with no significant craters.
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...

Sphere
A sphere is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in two dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface lying the same distance r from the center point...
