Barnard (lunar crater)
Encyclopedia
Barnard is a lunar
crater
that is located near the eastern limb of the Moon
. It is attached to the southeast rim of the large crater Humboldt
, and Abel
lies directly to the south. To the northeast is the crater Curie
, while to the southeast is the Mare Australe
.
The formation has been reshaped and distorted by nearby impacts. The interior is irregular, with an intrusion into the southwest rim and rugged formations particularly in the southern half. A matched pair of small craterlets lies near the center of the interior floor.
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...

Humboldt (crater)
Humboldt is a large lunar crater that is located near the eastern limb of the Moon. Due to foreshortening this formation has an extremely oblong appearance. The actual shape of the crater is an irregular circle, with a significant indentation along the southeastern rim where the prominent crater...

Abel (crater)
Abel is an ancient lunar crater that lies near the southeast limb of the Moon's near side. It is located to the south of the crater Barnard, at the northwest edge of the Mare Australe....

Curie (lunar crater)
Curie is a large lunar crater, much of which lies on the far side of the Moon as seen from the Earth. The western rim projects into the near side of the Moon, as defined by the selenographic coordinate system...

Mare Australe
Mare Australe is a lunar mare located in the southeastern hemisphere of the Moon. It is 603 kilometers in diameter, overlapping the near and far sides of the Moon. Smooth, dark volcanic basalt lines the bottom of the mare...

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 Barnard.| Barnard | Latitude | Longitude | Diameter |
