WebAug 1, 2005 · TLDR. An analysis of the comparatively sparse crater population on Jupiter's icy moon Europa finds that ‘secondaries’ (craters formed by material ejected from large primary impact craters) comprise about 95 per cent of the small craters on Europa, implying that the small crater populations on the Moon, Mars and other large bodies must be ... WebNo rayed craters were found in this study area larger than 500 m wide in diameter. However, rayed craters smaller than 500 m in diameter exist in Oxia Planum (e.g.: 18°20′30″N, 24°6′0″W) and there are possibilities for these craters to be included in further studies of the area at a smaller scale.
