Geological Chronicle
Barnard is a 115.7-kilometer lunar impact crater located near the eastern limb of the Moon. It is attached to the southeast rim of the large crater Humboldt, with Abel directly to the south, Curie to the northeast, and Mare Australe to the southeast.
Nearby impacts have reshaped and distorted the formation. The interior is irregular, with an intrusion into the southwest rim and rugged formations across the southern half. A matched pair of small craterlets lies near the center of the interior floor, while satellite craters Barnard A and B are attached to the southwest rim exterior.
The crater is named after American astronomer Edward Emerson Barnard, who discovered Barnard's Star in 1916. David W. G. Arthur and Ewen Whitaker introduced the name into lunar nomenclature with the 1963 Rectified Lunar Atlas, and its designation was formally adopted in 1964 by the International Astronomical Union.
