T. Mayer (crater)

T. Mayer, or Tobias Mayer, is a lunar impact crater that is located at the western end of the Montes Carpatus mountain range along the southern edge of Mare Imbrium. To the west is the Oceanus Procellarum, and to the south is Mare Insularum. The crater is located a couple of hundred kilometers to the northwest of the prominent crater Copernicus.

The name T. Mayer was first given to this crater by Johann Hieronymus Schröter in 1802.

T. Mayer and its surroundings


This crater is embedded within a region of rugged ridges and these are attached to the exterior of the rim, most notably along the east and northeast. The rim is generally circular with the bowl-shaped T. Mayer A attached to the exterior along the east-southeast. Within the interior is a level floor marked only by a few craterlets.

A couple of ray systems that originated from the Copernicus crater dominate the area of the crater, one is in the middle of crater and is nearly an east-west line going slightly north

Due south of T. Mayer is a cluster of lunar domes, some of which have tiny craterlets at the summits. These domes are the result of volcanic activity.
