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


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
