Aristillus and Autolycus (55/39 km) are two craters on the Moon's northern hemisphere. They are positioned so that they can be confused by those that are just beginning to know craters, with Aristoteles and Euxodus (87/67 km), which are located to the north-east, just that those are much larger.
Southwest of the two, is located Archimedes (83 km), with a smooth crater floor because it was flooded by lava.
