Theophrastus is a small lunar impact crater at the southern part of the Sinus Amoris, a bay at the northeast part of the Mare Tranquillitatis. It was named after ancient Greek philosopher Theophrastus in 1973. [2] It lies to the southeast of the lava-flooded crater Maraldi, and was designated Maraldi M until the IAU gave it its current name. Just to the southeast of Theophrastus is the flooded Franz.

This is a circular crater, with inner walls that slope down to the midpoint and a rim that rises slightly above the surrounding lunar mare. The crater has nearly the same low albedo as the nearby surface. It has no other distinctive features, and is not significantly eroded.

Spurr is the lava-flooded remains of a lunar impact crater. It was named after American geologist Josiah Edward Spurr. It is located in the midst of the Palus Putredinis plain, to the southeast of the crater Archimedes. Only the southern half of the rim protrudes significantly through the lunar mare material, while the northern section of the wall has a resemblance to a ghost crater rim.

Brackett is a small lunar impact crater that lies near the southeast edge of Mare Serenitatis. The crater is named after American physicist Frederick Sumner Brackett. The crater has been covered by lava flow, leaving only a ring-shaped trace in the surrounding lunar mare. This crater is best observed under oblique illumination, as it is otherwise difficult to find. The southern rim is almost contacting a rille system named the Rimae Plinius.

Mons Vinogradov is a rugged massif that is located on the lunar mare where Oceanus Procellarum to the southwest joins Mare Imbrium to the east.
