Daphnis, a small moon of Saturn, orbits within the Keeler Gap and exerts a noticeable gravitational pull on Saturn’s rings. This effect creates striking wave-like patterns along the ring edges, offering a visual glimpse into gravitational interactions in planetary systems.

    This image of shadows on the rings and others like it (see PIA11656 and PIA11655) are only possible around the time of Saturn’s equinox which occurs every half-Saturn-year (equivalent to about 15 Earth years). The illumination geometry that accompanies equinox lowers the sun’s angle to the ringplane and causes out-of-plane structures to cast long shadows across the rings.

    Super cool to read about this. Thanks for sharing
