Boethius is a small lunar impact crater located on the east edge of Mare Undarum near the eastern lunar limb. To the southwest is the dark, lava-flooded crater Dubyago. Boethius is circular and cup-shaped, with inner walls sloping down to the tiny central floor. It has a higher albedo than the surrounding terrain, and is not overlain by other impact craters of note. It was named after the Roman philosopher Boethius. Before 1976, it was identified as Dubyago U. References External links LTO-63D1 Boethius — L&PI topographic map Impact craters on the Moon
