Marci (crater)
Encyclopedia
Marci is a small, mostly unremarkable lunar
crater
on the far side of the Moon
. It is located about one crater diameter to the west of the prominent crater Jackson
. To the northwest of Marci is the larger crater Fitzgerald
.
This is a roughly circular, bowl-shaped feature with slight outward bulges in the rim to the north and south. The inner walls are generally simple slopes the run down to the interior floor. This floor is about half the diameter of the crater. Marci lies within the bright ray system
that surrounds Jackson.
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...

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...

Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Marci.| Marci | Latitude | Longitude | Diameter |
