Lobachevsky is a lunar impact crater that is located on the far side of the Moon, beyond the eastern limb. This crater lies to the southeast of the larger Fleming crater. Less than a crater diameter to the east-northeast lies Guyot crater.
This is a well-formed crater with features that have not been significantly eroded since Lobachevsky was first formed. The rim and inner wall are nearly free of significant overlapping impacts, although the satellite crater 'Lobachevsky M' is attached to the southern outer rim. The inner walls display terrace features, along with some slumping along the upper edge.
Near the mid-point of the interior floor is a pair of central peaks, with one to the southeast and the other to the northwest of the middle. To the east of these peaks is a relatively bright, high albedo patch that is most likely the result of a recent small impact.
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 Lobachevskiy crater.
