Jupiter

 

Jupiter is the 5th planet from the sun, and by far the biggest in size. The planet was named after the Greek god Zeus. Galileo discovered Jupiter in 1610 through his invention of the telescope. Winds of 600 km/h (373 mph) are very likely. One storm called the Great Red Spot, the size of three Earths, has been raging for three recorded centuries. New observations show that another may also soon form.

The atmosphere is composed of 90% hydrogen and 10% helium. The perihelion of Jupiter is 740,742,598 km and its aphelion totals to 816,081,455 km. By far, Jupiter has a high number of moons; 63! The surface gravity is 23.12 m/s2, as its 1.326 g/cm3. The size of Jupiter is tremendous. It's diameter us 142,984 km, enough to fit 11 Earths inside it! The rotation period, or day, on Jupiter is 9 hours and 55 minutes. The year is 4,333 Earth days.
