JUPITER-jupiter is The largest and The fifth planet from the sun.The diameter of Jupiter is 11 times larger than Earth's and only 10 times smaller than sun.From the Earth Jupiter appears quite bright because of its albedo of 0.343.telescopic observation reveal that Jupiter has a band of appearance.jupiter has four major satellites, which were discovered by Galileo,in addition to at least 12 smaller ones, which are discovered by flyby space probes and recent observation. Jupiter has been explored by several United States space probes.The first were the pioneer 10 and pioneer 11 missions, which arrived at Jupiter in 1973 and 1974, respectively.In 1979,the Voyager 1 and Voyager 2 missions discovered several new satellites or moons and a thin, dim ring around Jupiter.They also detected volcanic activity on jupiter's closest major moon,IO.In 1995, the United States spacecraft Galileo arrived at Jupiter and dropped a probe into the clouds while the main spacecraft orbited the planet for five years and made observations. (2) Jupiter atmosphere-jupiter has low density atmosphere,1326kg/m3, for its huge size because it is composed of light weight elements.hydrogen and helium make up the majority of jupiter's atmospheric gas.Below the liquid hydrogen,there is a layer of LIQUID METALLIC HYDROGEN, a form of hydrogen that has properties of both liquid and metal, which can exist only under conditions of very high pressure.Electric currents Flow within the layer of liquid metallic hydrogen and generates jupiter's magnetic field.Theoritical models suggest that Jupiter might have an earth sized solid core made of heavier elements that have sunk to the center of planet
SATURN
edit(1) Atmosphere- Saturn is not quite as large as Jupiter and has an average density that is actually lower than that of water.Similar to jupiter, Saturn rotates rapidly for its size and has flowing belts and zones.saturn atmosphere is dominated by hydrogen and helium, but it also includes ammonia ice near the top of clouds.The internal structure of sartun is also probably similar to jupiter.It is most likely fluid throughout with a small, solid core and a magnetic field is alighned with its rotational axis, which is unusual among the planets Derro444 (talk) 16:26, 21 May 2021 (UTC)
