Saturn

Sixth planet from the Sun, famous for its spectacular ring system of ice and rock particles.

Core Principles & Analysis

• Saturn's average density is less than that of water, the lowest of any planet.
• Cassini's 2017 Grand Finale orbits measured the rings' mass, suggesting they may be only tens to hundreds of millions of years old.
• A persistent hexagonal jet stream about 30,000 km across circles Saturn's north pole.
