Lobachevskiy 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 crater Fleming. Less than a crater diameter to the east-northeast lies Guyot. This is a well-formed crater with features that have not been significantly eroded since Lobachevskiy was first formed. The rim and inner wall are nearly free of significant overlapping impacts, although the satellite crater Lobachevskiy M is attached to the southern outer rim. The inner walls display terrace features, along with some slumping along the upper edge. Near the midpoint 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. Two dark ribbons of material apparently emanate from the base of a small crater in the western wall of Lobachevskiy, and this was observed on the Apollo 16 mission.〔Apollo 16 Preliminary Science Report (NASA SP-315), 1972, Figure 28-23〕 ==Views== Image:Lobachevsky crater AS11-43-6450.jpg|Low-altitude oblique close-up from Apollo 11 Image:Lobachevskiy crater AS14-75-10306.jpg|Oblique Apollo 14 Hasselblad camera image Image:Lobachevskiy crater AS16-M-1322.jpg|Oblique Apollo 16 Mapping camera image File:Lobachevskiy crater wall ribbons AS16-P-5022.jpg|Small crater in the wall of Lobachevskiy with distinct flow lobes 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lobachevskiy」の詳細全文を読む スポンサード リンク
