Daphnis is a small, football-shaped moon of Saturn, discovered in 2005. It orbits within the Keeler Gap, a narrow opening in Saturn’s A ring. Due to its gravitational influence, Daphnis disturbs nearby ring particles, generating distinctive wave-like patterns that both lead and follow its path. These formations, often referred to as “Daphnidian waves,” are striking evidence of the dynamic interactions between moons and planetary rings. Daphnis’s gravitational pull sculpts the surrounding ring material, earning it the nickname “shepherd moon.”
