As the largest planet in the solar system, how big and terrifying is Jupiter? The truth is beyond imagination.
There are a total of 8 large planets in our solar system, the largest of which is Jupiter. Jupiter is also the second largest object in the solar system, after the Sun. Jupiter has a very large mass, up to 18982 10 27 kg, which is 317 of the mass of the Earth8 times the Sun's 1 1047. In the entire solar system, in addition to the Sun, the mass of billions of celestial bodies is only 2 5 times the mass of Jupiter. In comparison, even Saturn, the second most massive, has only 29 of Jupiter's mass94%, and Neptune, ranked 3rd, has only 5 of Jupiter's mass4%。Since Jupiter has a very large mass, Jupiter's gravitational pull is also very high. The gravitational pull on the surface of Jupiter is 2479 meters square second, which is 2528 times. Due to Jupiter's very strong gravitational pull, Jupiter has 95 moons, of which the mass of the most massive moon is 1 40 of Earth and 9 20 of Mercury. Jupiter's gravitational pull can even affect the asteroid belt.
Jupiter is very large in volume and it has a volume of 14313 10 15 cubic kilometers, 1316 times the size of the Earth, 1 985 times the Sun. Although Jupiter's mass is only 1,1047 times that of the Sun, this is already large for the Sun. Jupiter's strong gravitational pull pulls the center of mass of the solar system to 1 distance from the center of the Sun07 The position of the solar radius. If Jupiter had 80 times the mass it has now, it could even become a star.
Jupiter is 1,316 times the size of Earth, but its mass is only 317 times that of Earth8 times, this is because the average density of Jupiter is much smaller than that of Earth. The average density of Jupiter is only 1326 10 kg cubic meters, which is 1 4 of the average density of the earth. This is because Jupiter is a gaseous celestial body, and its atmosphere is very thick, 5,000 kilometers thick. In Jupiter's atmosphere, 81% is hydrogen, 18% is helium, and the remaining 1% is other gases. The temperature difference between the equator and the poles on Jupiter is not large, no more than 3. The wind direction on Jupiter is rarely north-south, mainly east-west, and the fastest wind speed is 130-150 meters per second. The Great Red Spot is the largest storm on Jupiter and the largest in the solar system. The Great Red Spot has an area equivalent to 3 4 of the Earth's surface area, is 20,000 kilometers long and 11,000 kilometers wide, and is located at 23° south latitude of Jupiter, and can roll up cloud towers up to 8 kilometers high, and rotate in a counterclockwise direction, and it takes 6 Earth days (14 Jupiter days) to rotate one revolution.
Jupiter, although large, rotates quickly. Jupiter's rotation speed at the equator is as high as 1266 kilometers a second, which is 27 times that of the Earth23 times. Jupiter's upper atmosphere has poor rotation, with the poles rotating about 5 minutes longer than the equator. Due to Jupiter's high-speed rotation, Jupiter appears as an oblate sphere. Jupiter has an oblateness of 006487, is the 19th of the earth35 times.
Jupiter's core is very hot and dense. The temperature at Jupiter's core is as high as 24,000 and the density is 25 10 4 kg cubic meters.
