Eponym | Anders Johan Lexell |
Lexell is a lunar impact crater that lies across the southeastern rim of the huge walled plain Deslandres, in the southern part of the Moon. It was named after Swedish-Russian mathematician and astronomer Anders Johan Lexell.[1] To the northeast is the walled plain Walther, and to the south is Orontius, another 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 overlain 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.
Satellite craters[]
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Lexell.
