As we all know, the Sun is the only star in the Solar System, accounting for 4,993,5000 of the total mass of the Solar System, which is 333,050 times that of the Earth. The temperature on the surface of the sun is as high as 572685, which is 2726 higher than the boiling point of iron85℃。The core temperature of the sun is as high as 1499976385 and the density is 15 10 5 kg cubic meters (150 times that of water). The Sun's atmosphere contains 7346% hydrogen and 2485% helium, the rest of the gases are oxygen, carbon, iron, etc. The average density of the Sun is 1408 10 kg cubic meters (is gradually shrinking, about 1 4 of the earth, 1 of the water.)408 times). The volume of the Sun is 1412 10 18 cubic kilometers (gradually expanding), which is 1303536 times the size of the Earth.
Although there are billions of celestial bodies in the solar system, they cannot form a single star because they account for only 75,000 of the mass of the entire solar system.
Jupiter is the second most massive object in the solar system, it has a mass of 18982 10 27 kg, which is 317 of the Earth8 times, which is also 2. of the total mass of all other celestial bodies in the solar system except the Sun (the other seven planets, all moons, all comets, all asteroids, all dwarf planets, and all other matter).5 times. Despite its mass, Jupiter did not become a star.
Jupiter's atmosphere contains 90% hydrogen, 9% helium, and 1% other gases, very similar to the Sun. However, the mass of Jupiter is still not large enough. Jupiter's mass though is 317 of the Earth8. 2. The total mass of all celestial bodies except the Sun5 times, but it is very small compared to the Sun, only 1 1047 times that of the Sun. 2Mass J0523-1403 is the least massive star known. It is much smaller, only 71 of Jupiter's45%, 1 1379 of the Sun. But its mass is much greater than that of Jupiter, 77 times that of Jupiter and 7 times that of the Sun3%。Due to the very small mass of 2MASS J0523-1403, its surface temperature is also very low, only 1800, and the luminosity is only 1 80000 of the sun.
At least 007-0.It takes 08 solar masses for a celestial body to become a star, while Jupiter has a mass of only 0000954 solar mass. In other words, Jupiter would have to be at least 80 times more massive than it is now to become a star.
The surface temperature of the Sun is 572685,2Mass J0523-1403 has a surface temperature of 1800, while Jupiter's surface temperature is only -108, so Jupiter is unlikely to be a star.
Although Jupiter is not a star, it has many moons, numbering 95, so it is called the "Little Solar System". Jupiter is also known as the "star of failure".
