Jupiter in the solar system

Jupiter is the largest and fastest rotating planet among the eight planets in the solar system, and the fifth planet from the inside out. Its mass is one thousandth of that of the sun and 2.5 times that of the other seven planets in the solar system combined. Jupiter, Saturn, Uranus and Neptune are all gaseous planets, so they are also collectively called woody planets (Jupiter and Saturn are collectively called gaseous giants). Jupiter is a gas giant planet, accounting for 70% of all planets in the solar system. The main component is hydrogen, followed by helium, accounting for 25% of the total mass. The core contains other heavier elements. What humans usually see is the cloud top in the atmosphere, and the air pressure is slightly higher than 1 atmospheric pressure.

Jupiter is a giant liquid hydrogen star. With the increase of depth, liquid hydrogen is formed in the high pressure and high temperature environment at a distance of 1000 meters from the surface. It is speculated that the center of Jupiter is a nuclear region composed of silicate and iron, and the composition and density of matter are in constant transition.

Jupiter may be big, but it rotates faster than any other planet. Spinning at nearly 30,000 miles an hour! Because of this speed, Jupiter's day is only 10 hours! This incredible speed even led to the remarkable expansion of the area near Jupiter's equator.

Jupiter's most famous feature, the red dot, is a violent and huge storm. The storm is big enough to accommodate the earth with three diameters. The "red dot" has a history of more than 350 years, and there is almost no sign that it will slow down at any time!

According to the observation results, scientists found the most obvious red area in Jupiter's Great Red Spot, which confirmed the theory that there is a hot core inside the cold storm system. The black line on the edge of the storm in the observation image shows that the gas released by the storm is spreading into the planet.

The temperature in Jupiter's inner center is as high as 280 thousand K, which has reached the temperature required for thermonuclear reaction, but the pressure in Jupiter's inner center has not yet reached the requirements for thermonuclear reaction. According to scientists' observation, the air pressure in Jupiter's inner center has been rising for several years. Billions of years later, the pressure in the central region of Jupiter may meet the requirements of thermonuclear reaction. At that time, Jupiter, which has the basic conditions of thermonuclear reaction, will change its internal heat production capacity from the original way to nuclear fusion, and the swirling atmosphere will be a huge "emitter" for energy generated by nuclear fusion inside Jupiter, releasing energy continuously. Therefore, scientists speculate that Jupiter will change from a planet to a star in a few billion years.
