Which planet is known for its Great Red Spot?

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

Answer: (A)

A gigantic, long-lived storm in a gas giant’s atmosphere. The Great Red Spot is a colossal anticyclonic storm on Jupiter that has raged for centuries and is large enough to contain multiple Earths. Its persistence comes from Jupiter’s strong internal heat and the planet’s dynamic, banded atmosphere, where rapid rotation drives powerful jet streams that trap and sustain the storm. The red coloration is due to chemical compounds in the upper atmosphere altered by sunlight. Among the planets listed, Jupiter uniquely hosts this defining, enduring feature, while Mars has no such mega-storm, Saturn has storms but not this iconic spot, and Neptune’s weather is different in character. So the planet known for the Great Red Spot is Jupiter.
