Which planet is known for the Great Red Spot?

• A. Jupiter
• B. Saturn
• C. Mars
• D. Mercury

Answer: (A)

The Great Red Spot is a clue about where you’d find this feature: it sits in Jupiter’s atmosphere. Jupiter, a gas giant with a thick, layered atmosphere and no solid surface, spins very quickly. That rapid rotation, along with turbulent atmospheric dynamics, fuels enormous, long-lasting storms that create the planet’s famous banded appearance. The Great Red Spot is gigantic—larger than Earth—and has persisted for centuries, a testament to how storms behave in a world without a solid ground to interrupt them. Other planets listed have storms or red tones, but they don’t host this iconic feature: Saturn has its own storms and rings, Mars has dust storms on a rocky surface, and Mercury has very little atmosphere. So this persistent, iconic storm belongs to Jupiter.
