Barrow is an old lunar

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...

. It lies between the crater Goldschmidt

Goldschmidt (crater)

Goldschmidt is a large lunar crater of the variety commonly termed a walled plain. It lies in the northern part of the Moon's near side, and appears oval in shape due to foreshortening. The rim is actually relatively circular, although the western rim is overlain by the prominent crater Anaxagoras...

 to the northwest and the irregular formation Meton

Meton (crater)

Meton is a compound formation on the Moon that consists of several merged crater rings that have been flooded with lava, forming the remnant of a walled plain in the shape of a clover leaf. It is located near the northern lunar lumb, and is viewed from a low angle and foreshortened. The crater...

W. Bond (crater)

W. Bond is an irregularly shaped lunar walled plain that is located in the northern part of the Moon, to the north of the Mare Frigoris. It lies to the east of the crater Birmingham, and south-southwest of Barrow. Epigenes is located just to the northwest of the outer rim. Along the southwest edge,...

.

The outer wall of Barrow has been heavily eroded by subsequent impacts, and reshaped by intruding craters. As a result the rim now resembles a ring of rounded hills and peaks surrounding the flat interior. The younger satellite crater Barrow A lies across the southwest rim. At the eastern end of the crater is a narrow gap in the rim that joins the floor to the adjacent crater Meton. The rim achieves its maximum height and extend in the northwest, where it is joined to Goldschmidt.

The interior of Barrow has been resurfaced by lava

Lava

Lava refers both to molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling. This molten rock is formed in the interior of some planets, including Earth, and some of their satellites. When first erupted from a volcanic vent, lava is a liquid at...

 flows, leaving a flat surface that is marked by many tiny craterlets. Faint traces of ray material

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...

Anaxagoras (crater)

Anaxagoras is a young lunar impact crater that is located near the north pole of the Moon. It lies across the larger and more heavily worn crater Goldschmidt. To the south-southeast is Epigenes, and due south is the worn remains of Birmingham....

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 Barrow.
