210:. On Earth, radiation is deflected by the global magnetic field and attenuated by the atmosphere. The Moon however lacks both of these things and radiation, unimpeded, will darken the surface over time. It is thought then that a localised magnetic field will create a 'mini-magnetosphere', having locally the same effect as a global field might. This protection means that the surface at Gerasimovich is optically youthful compared to the surrounding landscape, which is what is seen as lunar swirls.

The outer rim of this crater is worn and eroded, with a perimeter that has been modified and reshaped by nearby impacts. The much younger crater
Gerasimovich D lies across the northeastern rim, and lies near the center of a poorly organized blanket of higher

Gerasimovich is home a powerful magnetic anomaly. This an area of the Moon that contains an unusually strong, localised magnetic field on a body that lacks a global dipole like that of the Earth. As such, the crater hosts an enigmatic feature known as a
