1,300 Earths would fit inside. Jupiter has no surface: this is a map of its clouds on one day in December 2000. Its Great Red Spot, a storm, is wider than the Earth, and 1,300 Earths would fit inside the planet.

What you’re seeing
Cassini photographed Jupiter’s clouds as it flew past in December 2000, on its way to Saturn. There is no ground beneath them.
Named places
Great Red Spot: A storm that has blown for at least 190 years. When Cassini made this map in 2000 it was about 20,000 km across; it has been shrinking, and is now only a little wider than the Earth.
North Equatorial Belt: A dark belt of sinking cloud. Jupiter turns in under 10 hours, which stretches its weather into bands right round the planet.
Equatorial Zone: A pale zone of rising cloud, topped with ammonia ice, where the winds blow eastward at over 300 km/h.
South Equatorial Belt: The dark belt the Great Red Spot sits in, as if it were a pebble in a stream. Every few years it fades almost white, then darkens again.
North polar cyclones: Juno found eight storms circling one at the north pole, each thousands of kilometres across, packed together like the cells of a honeycomb.
South polar cyclones: Around the south pole, Juno found a ring of five or six cyclones around a central one, held in a pattern no one expected.
