Jupiter
Jupiter is the fifth planet from the Sun, and the largest in the Solar System. It is a gas giant with a mass nearly 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun. The diameter of Jupiter is 11 times that of Earth and a tenth that of the Sun. It orbits the Sun at a distance of 5.20 AU (778.5 Gm), with an orbital period of 11.86 years. Jupiter is the third-brightest natural object in the Earth's night sky, after the Moon and Venus, and has been observed since prehistoric times. It was named after Jupiter, the chief deity of ancient Roman religion.
