Anaximenes is a low-rimmed
lunar impact crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact crater ...
near the north-northwest limb of the
Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width ...
. It lies to the west of the crater
Philolaus, and northeast of
Carpenter. To the northwest is
Poncelet, close to the visible edge of the Moon.
The outer rim of Anaximenes has been eroded and worn into a roughly circular ring of ridges. The rim is lowest along the northeast side where Anaximenes partly overlaps the equally worn satellite crater Anaximenes G. There are also low cuts through the rim along the southeast, where the crater is attached to an unnamed plain in the surface.
The interior floor of Anaximenes is relatively level, compared to the typical lunar terrain. The inner surface is pock-marked by a multitude of tiny craterlets of various dimensions, the most notable having a diameter of 2-3 kilometers.
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 Anaximenes.
