Eponym	Anders J. Lexell

Lexell is a lunar crater that lies across the southeastern rim of the huge Deslandres walled-plain, in the southern part of the Moon. To the northeast is the Walther walled-plain, and to the south is the Orontius walled-plain.

This is a somewhat irregular formation with a wide break in the northern rim. The western rim forms a low, arcing wall, and is overlaid to the southwest by 'Lexell H' after passing the rim of Deslandres. The rim peaks along the southeast, then comes to an end at a rugged promontory-like ridge. The interior floor has been resurfaced by lava to the northwest and in sections of the remainder of the floor. There are some low rises and ghost-crater rims in the southeast half part of the interior floor.

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 Lexell crater.
