Which planet is known for a prominent north-pole hexagonal cloud pattern and has the lowest density among planets?

• A. Jupiter
• B. Saturn
• C. Neptune
• D. Uranus

Answer: (B)

The distinctive north-pole hexagon reveals how Saturn’s atmosphere can organize into a stable, geometric wave pattern, a feature created by the planet’s jet streams and interior dynamics rather than by solid boundaries. This long-lived hexagonal storm is unique to Saturn and stands out as a hallmark of its atmospheric behavior. At the same time, Saturn has the lowest mean density of all the planets—lighter than water on average—so it would float if there were a giant enough ocean to test it. The other gas giants don’t share this hexagonal north-pole feature, and their densities are higher, with their polar regions showing different patterns. This combination of a famous hexagonal cloud pattern and the record-low density is what sets Saturn apart.
