How massive is Jupiter that it can become a star?

Jupiter, which is 80 times more massive than today, could become a star.

Jupiter is composed of 90 parts hydrogen and 10 parts helium (the ratio of atomic numbers, 75 to 25 mass ratios) and trace amounts of methane, water, ammonia, and "stones". This is very similar to the composition of the primordial solar system nebulae that formed the entire solar system. Jupiter coincides with the maximum diameter that a gas planet can reach.

If the composition is increased again, it will be compressed by gravity, increasing the global radius only slightly. A star can only grow in size because of the internal heat source (nuclear energy), but for Jupiter to become a star, the mass needs to be at least 80 times larger.

I remember that the lower limit of mass for the formation of stars is times the mass of the sun.

The lower limit of mass for the formation of stars is the mass of the Sun.

The criterion for the formation of stars doesn't seem to be mass, right?!

A star is supposed to be a celestial body that emits energy from its own nuclear fusion.

If a star much larger than the Sun collapses, that is, shrinks sharply to the core, the end result may be that it is still more massive than the Sun, but does not emit energy,,, it seems to be called a white dwarf???

I don't remember very clearly.,It's still a book I read when I was a child.。。。

MS is mass-determined, and when the mass reaches a certain level, the pressure and temperature inside the planet reach a certain level, and the nuclear fusion reaction can occur.

I got the information upstairs.

How credible is that?

Jupiter cannot become a star. Because in our solar system, there is simply not enough material to provide Jupiter to make it a star, as mentioned earlier, Jupiter's mass is equivalent to the other seven planets combined, and the mass of the other dwarf planets, asteroids, moons, comets, etc. is not much combined.

That is to say, in addition to the sun, Jupiter's mass accounts for a large part of the solar system, and the other parts are not as large as the mass of a Jupiter, so it is impossible to double the mass of Jupiter in the solar system, let alone increase it by 80 times, so it is impossible for Jupiter to become a star in the foreseeable future.

A brief introduction to the rest of Jupiter.

Jupiter is a giant planet with a mass of one-thousandth the mass of the Sun, but twice the mass of the other planets in the solar system combined. Jupiter's main component is hydrogen, but helium, which accounts for only one-tenth of the molecular quantity, makes up a quarter of the total mass; It may have a rocky core and heavy elements, but no solid surface that can be clearly defined. Due to its rapid rotation, Jupiter's appearance appears as an oblate sphere.

The atmosphere is divided into different zones and zones depending on latitude, and there are turbulence and storms at the junction of each other.

Summary. Kiss, in nature, Jupiter does not become a star. Among the eight known planets in the solar system, Jupiter is indeed a "giant", and the combined mass of the other planets is only 40% of Jupiter, less than half.

Although Jupiter's composition is very similar to that of stars, Jupiter's mass is still too low, and what kind of mass will determine what kind of celestial body. As a star, the Sun has a mass 1,000 times that of Jupiter, which is equivalent to the total mass of all objects in the solar system. So in nature, Jupiter does not become a star.

Kiss Extension: Jupiter is the largest and fastest rotating planet among the eight planets in the Qingchuqiao Solar System, and the fifth planet from the inside out. It has a mass of one-thousandth the mass of the Sun and a mass of the other seven planets in the Solar System combined.

Jupiter, Saturn, Uranus, and Neptune are all gas planets, so they are also called Jupiter-like <>

It is more than 1.3 million times the size of the Earth. Jupiter: Jupiter has the largest volume and mass among the eight planets in the solar system, and it has an extremely huge mass, more than twice that of the other seven planets combined, 318 times that of the Earth, and 1,321 times the volume of the Earth.

Compared to the Sun, Jupiter is indeed a bit of a "small thing". Jupiter, which is known as the "hegemon" of other planets, is only 1/1000th the volume of the Sun, with a mass of only 1,1047 of the Sun, that is, about the mass of the Sun, and the central temperature is only 1/500th of the Sun.

The mass of the Sun is kg, the mass of the Sun is 1047 times that of Jupiter, 1047 Jupiter is comparable to one Sun, and 1 1047 Suns are comparable to one Jupiter.

Mass: kg.

Average density: water is 1).

Core density: 160 (1 for water).

Among the eight planets in the base solar system, it has the largest volume and mass, and it has an extremely large mass and vertical mass, which is more than twice that of the other seven planets combined, and is twice that of the Earth, and its volume is 1,316 times that of the Earth.

Jupiter is the most massive planet. This statement is true.

Jupiter is the fifth closest planet to the Sun in the Solar System and the largest planet in the Solar System. The ancients had known about the planet for a long time, and the Romans named it after the main god Jupiter. In ancient China, Jupiter was called the star of the year, and it was said that it orbited the celestial sphere for about 12 years, which is the same as the earthly branch.

In the Western Han Dynasty, Sima Qian, the author of the "Historical Records of Tianguanshu", found that the star was cyan from actual observation, which was associated with the "Five Elements" doctrine, and officially named it "Jupiter". Jupiter can be seen from the Earth, with an apparent magnitude of up to magnitude, and it is already possible to cast shadows on the ground. Jupiter is the third brightest object in the night sky on average after the Moon and Venus.

Jupiter is a giant planet with a mass of one-thousandth the mass of the Sun, but twice the mass of the other planets in the solar system combined. Jupiter's main component is hydrogen, but only one-tenth of the number of m's and daughters' helium, but a quarter of the total mass; It may have a rocky core and heavy elements, but no solid surface that can be clearly defined.

Due to its rapid rotation, Jupiter's appearance appears as an oblate sphere. The atmosphere is divided into different zones of disadvantage according to latitude, and there are turbulence and storms at the junction of each other. The most striking example of this is the Great Red Spot, a huge storm that has not stopped since it was first seen by a telescope in the 17th century.

Roundup

Jupiter is a giant liquid hydrogen planetary body. As the depth increases, at depths of at least 5,000 km above the surface, liquid hydrogen forms at high pressures and temperatures. It is speculated that the center of Jupiter is a nucleus composed of materials such as silicates and iron, and the composition of the material is in a continuous transition from density.

Jupiter is a gaseous planet (also known as Jupiter-like), that is, a planet composed mainly of non-solid matter, it is the largest planet in the solar system, with an equatorial diameter of 142984 kilometers. Jupiter is the second densest of gas planets, but much lower than the four terrestrial planets in the solar system.

Analysis: Earth's mass 10 24 kg Jupiter's kilogram Jupiter's mass is 318 times the Earth's mass.

Jupiter is a representation of giant planets: the equatorial radius is about 71,000 kilometers, 11 times the radius of the Earth; It is 1,316 times the size of the Earth; The mass is 318 times the mass of the Earth, which is twice the mass of the other eight planets combined. Its density is grams per cubic centimeter, which is only 1 4 of the density of the earth.

Its equatorial rotation is only 9 hours, 50 minutes and 30 seconds, making it the fastest rotation among the nine planets. Its equatorial circumference is nearly 450,000 kilometers, and it takes less than 24 hours to make one revolution, so its equatorial part is prominent, and it has an oblate spherical body.

Jupiter also has rings. The Great Red Spot in Jupiter's atmosphere is a vigorous updraft moving in a counterclockwise direction, and this air flow contains a large amount of red phosphide in the material, so it is red. This Great Red Spot Leaky Foot can hold two Earths.

Jupiter also has a strong magnetic field and radiation belts, and there are also auroras in the atmosphere. In terms of evolutionary system, Jupiter itself can also emit some light, and it may be between stars and terrestrial planets.

Jupiter's huge body and mass pulled Comet Shoemaker Levy 9 to its side and shattered the comet nuclei, causing these comet nucleus fragments to hit it at a speed of about 60 kilometers per second for six days, but Jupiter was as stable as ever, safe and sound.
