It lies in the northern outskirts of the huge walled plain Hertzsprung, to the southwest of the crater Fersman and southeast of Poynting. The rim of this crater is generally circular, with a small impact crater intruding into the eastern edge. A small crater fills the northwestern part of the interior floor. Satellite cratersBy convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Grigg.
