Barrow is an old lunar impact crater
An impact crater is a depression (geology), depression in the surface of a solid astronomical body formed by the hypervelocity impact event, impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal c ...
that is located near the northern limb of the Moon
The Moon is Earth's only natural satellite. It Orbit of the Moon, orbits around Earth at Lunar distance, an average distance of (; about 30 times Earth diameter, Earth's diameter). The Moon rotation, rotates, with a rotation period (lunar ...
. It lies between the crater Goldschmidt to the northwest and the irregular formation Meton to the northeast. To the southwest is W. Bond.
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 is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a Natural satellite, moon onto its surface. Lava may be erupted at a volcano or through a Fissure vent, fractu ...
flows, leaving a flat surface that is marked by many tiny craterlets. Faint traces of ray material from Anaxagoras
Anaxagoras (; , ''Anaxagóras'', 'lord of the assembly'; ) was a Pre-Socratic Greek philosopher. Born in Clazomenae at a time when Asia Minor was under the control of the Persian Empire, Anaxagoras came to Athens. In later life he was charged ...

Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Barrow.References
