In the image taken on July 22, 2013, Saturn’s hexagon can be seen here in true color. It is a very large persisting hexagonal cloud pattern around the north pole of Saturn. The sides of the hexagon are about 8,600 miles (13,800 km) long, which is more than the diameter of Earth (about 7,900 miles / 12,700 km). Sometimes it is easy to forget just how large Saturn is: with a diameter of about 72,400 miles (116,500 kilometers), it is around 10 times wider than the Earth.
This view was acquired at a distance of approximately 611,000 miles (984,000 kilometers) from Saturn. Image source: NASA
