Saturn ♄

• 10 AU from the Sun
• Takes nearly 30 years to orbit the Sun
• Low density ($0.7 g/cm^3$)
  • Light enough to float in water (less dense)
    • Although it isn't solid so it wouldn't actually float
  • Lowest of any planet

Moons

• 62 known moons
• Members:
  • Titan
  • Enceladus

Ring System

• Very thin
  • 270 million metres x 20 m
• Collisions act to smooth everything out
• Icy rocks
  • Typically the size of ping-pong balls, tennis balls, and basketballs
• Some gaps from moons
• It's unlikely the rings were a destroyed moon
• Being close to Saturn's tidal forces prevents the formation of larger bodies
• E ring appears to be continually replenished by Enceladus
