Theon Senior is a lunar impact crater that is located to the northwest of Delambre crater, and south of D'Arrest crater. It forms a matching pair with the Theon Junior crater, about 2 crater diameters to the south-southeast. This crater is circular and bowl-shaped, with only a small floor at the center of the sloping interior walls. The crater appears relatively young, as it shows little sign of wear due to impacts.

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 Theon Senior crater.
