Scaliger (crater)
Encyclopedia
Scaliger is a prominent lunar
impact crater
that is located in the southern hemisphere
on the far side of the Moon
. It is attached to the northwest rim of the walled plain Milne
, and the shared perimeter has reshaped the outer wall of Scaliger slightly, producing a straightened section along the southeast. To the west of Scaliger is the Lacus Solitudinis
.
The outer wall of Scaliger is somewhat polygon
al in shape, especially in the southern half. The rim has not been heavily eroded by subsequent impacts, in contrast to the heavily worn Milne to the southeast. The inner wall of Scaliger's rim displays terraces, and a notable outer rampart overlaying the floor of Milne. The interior floor of Scaliger is relatively flat, with a rough surface near the inner wall. Near the mid-point is a central peak, offset slightly to the east.
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...

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...

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...

Lacus Solitudinis
Lacus Solitudinis is a small lunar mare on the far side of the Moon. The selenographic coordinates of the lake are 27.8° S, 104.3° E, and it lies within a diameter of 139 km. It forms an arcing feature with the concave side oriented to the northwest...

In geometry a polygon is a flat shape consisting of straight lines that are joined to form a closed chain orcircuit.A polygon is traditionally a plane figure that is bounded by a closed path, composed of a finite sequence of straight line segments...
