Blazhko (crater)
Encyclopedia
Blazhko is a lunar
impact crater
that is located in the northern hemisphere
on the far side of the Moon
. It lies to the northwest of the crater Joule
, and to the south of Gadomski
.
The rim of this crater is generally circular, but with some irregularities. There is a small outward bulge in the rim to the east-southeast, and an inward bulge on the opposite face. There is also a slight outward bulge along the north rim. The satellite crater Blazhko F is attached to the exterior of the east rim. The inner wall along the northeast face is striated with terraces. The interior floor is relatively level.
The satellite crater Blazhko T, located due south of Blazhko, has a higher albedo
than its surroundings, and possesses a ray system
. The most prominent of these rays extends southward, crossing the floor of the crater Harvey
.
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...

Gadomski (crater)
Gadomski is a lunar crater on the far side of the Moon. It is located to the south of the much larger crater Fowler, and to the west of Klute.This crater, like many features on the Moon, has an eroded outer rim that has been modified by subsequent impacts...

Albedo
Albedo , or reflection coefficient, is the diffuse reflectivity or reflecting power of a surface. It is defined as the ratio of reflected radiation from the surface to incident radiation upon it...
than its surroundings, and possesses a ray system
Ray system
A ray system comprises radial streaks of fine ejecta thrown out during the formation of an impact crater, looking a bit like many thin spokes coming from the hub of a wheel. The rays can extend for lengths up to several times the diameter of their originating crater, and are often accompanied by...

Harvey (crater)
Harvey is a lunar impact crater that is located on the far side of the Moon from the Earth. It lies astride the eastern rim of the much larger crater Mach, and the outer rampart of Harvey extends part way across the interior floor...
