Backlund (crater)
Backlund is a worn lunar impact crater that lies on the far side of the Moon, beyond the eastern limb. It lies astride the southern rim of the walled plain Pasteur, to the west of the crater Hilbert. Further to the west-southwest is Sklodowska. The north and south ends of Backlund are more worn and eroded than the intervening stretches. The interior floor is relatively flat, with the usual accompaniment of tiny impact craters marking the surface.
