Daphnis

Daphnis is a small moon orbiting Saturn, situated within its rings. Discovered in 2005, it measures about 8 kilometers across. Daphnis's gravitational influence creates ripple-like waves and gaps in Saturn's rings, especially within the A ring. These structures occur because Daphnis's gravity disturbs the ring particles, similar to how a boat moving through water creates ripples. Its presence helps scientists study ring dynamics and gravitational interactions in planetary systems. Despite its size, Daphnis plays a significant role in shaping the structure of Saturn's rings.
