Opelt is the lava-flooded remnant of a lunar crater on the Mare Nubium. It lies to the north of a similar formation named Gould crater, and to the northeast of the prominent Bullialdus crater.
Only a slightly raised outline remains of the Opelt crater rim, the interior having been inundated with lava. The rim has a wide break at the northern end and several smaller breaks to the south and southeast. The satellite craterlet 'Opelt E' lies at the southern end of the surviving western rim. The interior floor is nearly level, with the exception of a slight rise to the southwest.
To the north of Opelt on the lunar mare is a sinuous system of rilles designated Rimae Opelt. These occupy a diameter of about 70 kilometers.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Opelt crater.
