Is it possible to see the Plato crater on the Moon with the naked eye from the Earth, the diameter of which is 100 km? The resolution of the eye is taken equal to 1 ‘, the diameter of the Moon is 3480 km.
D / d = 30 / p; p = d * 30 / D; p = 100 * 30/3480 = 0.9 ‘. The crater will not be visible to the naked eye, since its angular dimensions are less than 1 ‘.
