To the southwest of Euctemon is the large walled plain Meton, and to the north-northeast lies the crater De Sitter.

Due to its location, Euctemon appears foreshortened when viewed from the Earth.

The interior floor of this crater has been resurfaced some time following the original formation, leaving a nearly level, featureless plain surrounded by the worn outer rim.

This floor is marked only by a number of tiny craterlets, and the small crater Euctemon K near the southwest inner wall.

Just to the north is another small crater, Euctemon H, that now forms a wide cleft through the rim.
