Omar Khayyam is a lunar crater that is located just beyond the northwestern limb of the Moon, on the far side from the Earth. It lies in a region of the surface that is sometimes brought into view of the Earth due to libration, and under favorable lighting it can be viewed from the edge. However under such circumstances not much detail can be seen, and the crater is best viewed from orbit.
This feature is located at the western edge of the larger Poczobutt walled-plain, and the northwestern rim of Omar Khayyam is overlaid by Zsigmondy crater. The east-southeastern part of the interior floor of Omar Khayyam is overlaid by a smaller and younger crater. The remainder of the interior floor is split in half by a ridge attached to the western outer rim of this crater, giving Omar Khayyam the appearance of a formation composed of multiple merged impacts.
The outer rim of Omar Khayyam is heavily eroded, and has a wide gap to the southeast. A small crater overlays the western rim, and multiple small craterlets mark the sides and parts of the interior. The floor to the southwest is somewhat smoother than elsewhere.
This crater was named in honor of Persian mathematician and astronomer Omar Khayyám.
