Ukert is a lunar impact crater that lies on a strip of rugged ground between Mare Vaporum to the north and Sinus Medii in the south. It was named after German historian Friedrich August Ukert. It is located to the north-northwest of the crater Triesnecker and northeast of the crater pair of Pallas and Murchison.

Murchison is a lunar impact crater on the north edge of the Sinus Medii. It was named in honour of the geologist Sir Roderick Murchison. It shares a section of rim with the crater Pallas. To the southeast on the mare is the circular crater Chladni, and to the northeast is Ukert. Farther to the east is the prominent Triesnecker. Murchison lies astride the lunar zenith line, i.e. the starting longitude of the selenographic coordinate system.
