The 'Great Red Spot', a giant storm larger than the Earth, is found on the planet:

The Great Red Spot is a huge, long-lived storm in Jupiter's southern hemisphere. It is a high-pressure system, called an anticyclone, with winds that blow at hundreds of kilometres per hour.

About the Great Red Spot:

• It has been observed continuously since at least 1830, and possibly since the 1660s, when early telescope observers noted a spot on Jupiter.
• It is so large that the Earth could fit inside it.

The storm has been shrinking over the past century. In the late 1800s it was about 40,000 km across; today it is roughly 15,000 to 16,000 km wide.

Its reddish colour is believed to come from chemicals in Jupiter's atmosphere that are broken down by sunlight, but the exact cause is still studied.

About Jupiter:

• Jupiter is the fifth planet from the Sun and the largest planet in the solar system.
• Its mass is more than twice the mass of all the other planets combined.
• It is a gas giant, made mostly of hydrogen and helium.
• It has faint rings, discovered by the Voyager 1 spacecraft in 1979.
• It has a very strong magnetic field and intense radiation belts.
• Jupiter acts like a "cosmic vacuum cleaner", as its strong gravity attracts or deflects many comets and asteroids.

Missions to Jupiter:

• Juno, launched by NASA in 2011, has been studying Jupiter since 2016.
• The European Space Agency's JUICE mission was launched in 2023 to study Jupiter's icy moons.
• NASA's Europa Clipper was launched in 2024.

Storms on other planets:

• Neptune had a "Great Dark Spot", seen by Voyager 2 in 1989, which later disappeared.
• Saturn shows a hexagon-shaped jet stream around its north pole.

Why not the other options?

• ✗Mars is called the Red Planet because of the reddish dust on its surface, not because of a storm.
• ✗Saturn and Neptune do not have the Great Red Spot.
