"Tycho (85 kilometres dia) is a comparatively fresh impact crater with a vast ray system of ejecta material spanning almost 1,500 kilometres across the lunar surface."
Copernicus (107 kilometres dia) - "Its striking terraced walls, grouping of small central peaks and radial ejecta rays out to 800 kilometres make it a stunning sight in any astronomical telescope."
Kepler (31 kilometres dia) - "Kepler is a small, young, lunar crater. Despite being just 31 km in diameter the crater and its associated system of rays is visible from the Earth." "The crater itself is 2.6 km deep and contains evidence for terracing and a central peak and is of similar age to the Lichtenberg crater, and the more widely known Copernicus and Tycho craters. In common with these last two, Kepler also contains a series of bright rays stretching around 300 km from the crater."
