Lacchini is an
impact crater on the
far side of the
Moon. It is located in the northern
hemisphere, just behind the northwestern limb of the visible Moon. This part of the lunar surface can sometimes be viewed under favorable conditions of
libration and illumination, but at such times the crater is only seen from the edge.
Less than one crater diameter to the east is the larger crater
Bragg. To the north is
Stefan, and farther to the southeast is the walled plain
Lorentz. Due west of Laccini is
Landau, another walled plain.
The outer rim of Lacchini is roughly circular, with outward bulges to the south and east. The edge is sharp and not significantly eroded. The inner walls have slumped around much of the circumference, forming an irregular ring of
talus about the interior floor. There are some low ridges near the midpoint and in the eastern half of the floor.
