Brenner is an old lunar crater that lies in the rugged southeastern part of the Moon's near side. It is named after the Serbian astronomer Spiridon Gopčević (who was also a publicist under the pen name of Leo Brenner) and is located within one crater diameter northwest of the crater pair Metius and Fabricius. Also Janssen is located to the south.
This ancient formation has been deeply eroded by subsequent impacts, to the point where only the western part still resembles a crater. That face has the most intact part of the rim, although it has been worn down until it forms a low ridge in the surface. The northeast part of the crater has been reshaped until it is little more than a rough, irregular part of the terrain. The southeastern rim is overlain by a relatively old crater designated Brenner A.
The crater is actually nearly circular. At this location, from Earth, the crater appears oval due to foreshortening but can rarely be seen, the view from Earth of the crater can only be seen with a telescope.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Brenner.
