Largest anticyclone in the Solar System

The Great Red Spot on the planet Jupiter is the largest anticyclone in the Solar System. It varies in size but can be up to 40,000 km (24,800 miles) long and 14,000 km (8,700 miles) wide.

It was first discovered in 1664 by Robert Hooke (UK) using one of the first telescopes. The clouds of the storm tower some 8 km above the surrounding cloudscape and the storm itself has maintained the same latitude, varying only by one degree.
