The Largest Planet in Solar System

Do you know jupiter ???? Jupiter is the largest of the giant gas planets, Jupiter, with a volume1.321 times greater than earth, contains more than twice the mass of all the other planets combined. It is thought to be gaseous and fluid planet without solid surfaces.  Had it been somewhat more massive, juoiter might have attained internal temperatures as high as the ignition point if nucear reactions, and it would have flamed as a star in its own right. Jupiter and the other giant planets are of a low-density typ quite distinct from the terrestrial planets, they are composed predominantly of such substance as hydrogen, helium, ammonia, and methane, unlike terrestrial planets. Much of jupiter‚interio might be in the form of liquid, metallic  hydrogen. Normally, hydrogen is a gas, but under pressure of millions of kilograms per centimeter, which exist in the deep interior of jupiter, the hydrogen atom might lock together to form a liquid with the propeties of a metal. Some scientist believe that the innermost core of jupiter might be rocky, or metallic like the core of Earth

Astronomers call Jupiter a failed star, but that’s not really appropriate. Stars generate their energy through the fusion of mass together. Their enormous gravity creates heat and pressure inside the star so that atoms of hydrogen are fused together to create helium – releasing heat in the process. Jupiter would need more than 70 times its current mass to ignite nuclear fusion.

Jupiter's enormous magnetic field is nearly 20,000 times as powerful as Earth's. Trapped within Jupiter's magnetosphere are swarms of charged particles. Jupiter's rings and moons are embedded in an intense radiation belt of electrons and ions trapped in the magnetic field. The Jovian magnetosphere, composed of these particles and fields, balloons 600,000 to 2 million miles (1 million to 3 million kilometers) toward the sun and tapers into a windsock-shaped tail extending more than 600 million miles (1 billion kilometers) behind Jupiter, as far as Saturn's orbit.

Jupiter rotates very fast, once every 9.8 hours. As a result, it clouds, which are composed largely of frozen and liquid ammnia, have been whipped into alternating dark and bright bands that circle the planet at different speeds in different latitudes. Jupiter‚puzzling great re spot changes size as hovers in thesouthern hemisphere. Scientist speculate it might be gigantic huricane, which because of its large size (the earth could easily fit inside it), last for hundreds of years.

Jupiter give off twice as much heat as it receives from the sun. Perhaps this is primeval heat bor beat generated by the continued gravitational contraction of the planet. Another starlike charateristic of jupiter is its sixteen natural satellites, which, like a miniature model of the solar system, decrease in density with distance from rocky moons close to jupiter to icy moons farther preserved sample of th early solar nebula, and with its satellites, might contain the most important clues about the origin of the solar system.
