Jupiter is so large that all of the other planets in the solar system could fit inside it. It’s the fifth planet from the sun and has a diameter of 88,846 miles. Astronomers estimate the core temperature at 20,000 degrees Celsius.

Jupiter’s atmosphere is made mostly of hydrogen and helium gases. Jupiter is a large gas planet whose clouds change colours daily. Darker clouds tend to be deeper in Jupiter's atmosphere, while the white clouds are higher. Large bolts of lightning have also been seen in Jupiter's atmosphere. The average temperature at the top of Jupiter's clouds is –117°C.

Also in Jupiter's atmosphere are oval features which are thought to be circular winds. The most prominent of these is the Great Red Spot, a hurricane-like storm that has been seen in Jupiter's southern hemisphere since Jupiter was first discovered.
