1, Jupiter is a gas giant planet, accounting for 70% of the mass of all planets in the solar system, mainly composed of hydrogen, accounting for 75% of its total mass, followed by helium, accounting for 25% of its total mass, and the rock core contains other heavy elements.

2. Jupiter is called a flexible fat man because it rotates very fast (when it rotates nine earths) and presents a flat sphere (with a slight but obvious bulge near the equator). The outer atmosphere is clearly divided into several regions according to latitude, and the boundary of each region is prone to turbulence and storms. The most obvious example is the Great Red Spot.

The mass of Jupiter is 2.5 times that of other planets in the solar system. Because of its huge mass, the center of mass of the solar system is located outside the surface of the sun, and the distance from the center of the sun is 1.068.

4. There are auroras at Jupiter's poles, which are formed by the material erupting from the volcano on Io entering Jupiter's atmosphere along Jupiter's gravitational line. Jupiter has a halo, and the halo system is the same feature of the giant planets in the solar system, which is mainly composed of black rubble and snow. Jupiter's rings are hard to observe. It is not as spectacular as Saturn, but it can also be divided into four circles.

5. Jupiter's magnetic field intensity is 14 times that of the earth, ranging from 4.2 gauss at the equator to 10 at the polar regions to 14 gauss. It is the strongest magnetic field in the solar system (except sunspots). The volcano of Eos satellite releases a large amount of sulfur dioxide, forming a gas ring along the orbit of the satellite. These gases are ionized in the magnetosphere, producing sulfur and oxygen ions.

Extended data

From March 2065438 to March 2008, the British magazine Nature recently published four papers on planetary science, detailing the new discoveries about Jupiter's characteristics, including its gravity field, atmospheric flow, internal composition and polar cyclone, which is the latest key achievement of NASA Jupiter probe Juno.

Although people have done a lot of research on Jupiter's surface (with obvious dark "areas" and bright "areas"), they still know little about its deep inside. In 20 16, Juno paid an official visit to Jupiter, which was the first time that human beings had the opportunity to observe the king of this planet very closely.

This time, the research team of the University of Rome made an in-depth study of Jupiter's gravity field by using Juno's Doppler tracking measurement data. Jupiter's polar gravity field is different. A high-speed rotating oblate fluid planet unexpectedly shows this north-south asymmetry, which the research team believes is caused by atmospheric flow and internal airflow.

The French research team analyzed Jupiter's "even-order" gravity field coefficient and found that more than 3000 kilometers below the clouds, Jupiter's deep interior is composed of hydrogen and helium, which rotate like a solid. Scientists have concluded that if the internal dynamics of Saturn and Jupiter can be physically coordinated, it will be of decisive help to further understand the internal dynamics of gas giants.
