Core Principles & Analysis

• Jupiter is more than twice as massive as all the other planets combined.
• The Great Red Spot has been observed continuously since 1831 and has been shrinking for over a century.
• NASA's Juno mission revealed a dilute, 'fuzzy' core of heavy elements mixed into the surrounding hydrogen rather than a compact center.
