What are some facts about Jupiter?

Jupiter is the fifth planet from the Sun and is the largest planet in the solar system. Because of the giant size of Jupiter, the gravity there is 2.4 times more than on Earth. If you weigh 100 pounds on Earth, you would feel like you weighed 240 pounds on Jupiter. Jupiter possesses 62 known satellites. The four largest are Callisto, Europa, Ganymede, and Io, and were named after Galileo Galilei who observed them as long ago as 1610. Jupiter has a very faint ring system but is totally invisible from the Earth. The atmosphere is very deep, perhaps comprising the whole planet, and is somewhat like the Sun. It is composed mainly of hydrogen and helium, with small amounts of methane, ammonia, water vapor and other compounds. At great depths within Jupiter, the pressure is so great that the hydrogen atoms are broken up and the electrons are freed so that the resulting atoms consist of bare protons. This produces a state in which the hydrogen becomes metallic.
