00:00Deep in the heart of Saturn's majestic ring system hides a tiny secret, a moon shaped like a walnut.
00:07This is Pan, a 17-mile wide world that acts as a cosmic shepherd.
00:13As it orbits through the Enki Gap, its gravity performs a delicate balancing act,
00:19sweeping the space clean of ice and dust while sculpting the sharp edges of the rings themselves.
00:26Pan's strange, bulging ridge was actually built by the rings it shapes,
00:31as it slowly vacuumed up stray particles over millions of years.
00:36This tiny moon proves that you don't need to be a giant to influence the architecture of the solar system.
00:43Sometimes, even the smallest gear is what keeps the entire celestial machine running in perfect harmony.
