(ENG) Kepler is a bright impact crater located not far from the equator. Its remarkable rays are less wide, but more contrasted than those of the "neighbor" Copernicus</a. The crater belongs to the most recent of the lunar geological periods, the Copernican, reserved to formations with an estimated age of less than a billion years. According to an hypothesis by Whitaker, Riccoli choose the names of the craters Kepler, Copernicus and Aristarchus for a very specific reason, explained in the page dedicated to Aristarchus.

Kepler and its rays

La raggiera che entra da Est, incrociandosi con quella di Kepler è quella di Copernico. Ad ovest, a ridosso del terminatore, è visibile il cratere Marius con i suoi domi.

(ENG) The rays coming from the East, crossing those of Kepler, belong to Copernicus. Close to the terminator, Marius crater with its domes is visible.
