JUPITER
It is the largest planet of the solar system.
The radius of the jupiter is 69 911 km kilometers.
Mass of the jupiter is about 311 times of the earth.
Density of the jupiter is 1.33 g/cm³.
Gravity of the jupiter is 24.79 m/s².
It is orbiting the Sun at a distance of 5.20 AU (1 AU = Average distance between Earth and Sun = 149,598,000 km) 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 it has been observed since prehistoric times. One jupiterian day is 9 hours and 55 minutes and one jupiterian year is 12 years (4 333 days).
Jupiter is surrounded by a faint planetary ring system and has a powerful magnetosphere, the second largest contiguous structure in the Solar System (after the heliosphere). Jupiter forms a system of 95 known moons and probably many more, including the four large moons discovered by Galileo Galilei in 1610: Io, Europa, Ganymede, and Callisto. Ganymede, the largest of the four, is larger than the planet Mercury. Callisto is the second largest; Io and Europa are approximately the size of Earth's Moon.
