The sun, like any other planet, is aged. Where is the sun at the moment?

In middle age, there is still a lifespan of 5 billion years. But the last few million years will turn into red giants that will scorch the Earth. But no human or species seems to have lived for more than 4 billion years. So don't worry.

The current main-sequence phase of the Sun has been going through about 100 million years through computer simulations of stellar evolution and cosmochronological models. According to research, the rapid collapse of a cloud of hydrogen molecules 100 million years ago formed a Taurus T star of the first generation of the first generation, that is, the Sun. The newborn star orbits in a near-circular orbit about 27,000 light-years from the center of the Milky Way.

The Sun has reached middle age in its main-sequence phase, during which the stellar nucleosynthesis reactions that occur inside its core fuse hydrogen into helium. At the core of the Sun, more than 4 million tons of matter can be converted into energy every second, generating neutrinos and solar radiation. At this rate, the Sun has so far converted about 100 Earth-mass matter into energy.

The time when the Sun is the main-sequence star lasts about 10 billion years. The mass of the Sun is not massive enough to explode into a supernova. In 5,06 billion years, when the Sun's hydrogen is depleted, the core is dominated by helium atoms, and the Sun will transform into a red giant, expanding its outer layers when the hydrogen in its core is depleted, causing the core to shrink and the temperature to rise.

When its core temperature rises to 100,000,000 K, helium will fuse to produce carbon, which will enter the asymptotic giant branch, and when all the helium in the Sun is converted to carbon, the Sun will no longer shine and become a dead star (Black Dwarf).

The sun is about 100 million years old. The Sun is a star located at the center of the solar system and occupies the overall mass of the solar system. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, which revolves around the center of the Milky Way.

The Sun is a yellow dwarf, and the lifespan of a yellow dwarf is roughly 10 billion years, and the Sun is currently about 100 million years old.

The remains of meteorites were found from Earth, and the oldest meteorite was also found to be 4.9 billion years old, and the meteorite came from any part of the solar system and was also younger than the sun. And the age of the sun is not too far away, scientists speculate that the current age of the sun is about 4.6 billion to 4.8 billion years. The Sun is now in a solid middle age.

In about 50 to 6 billion years, the Sun's interior will be almost completely depleted of hydrogen and the Sun's core will collapse, causing the temperature to rise, a process that will continue until the Sun begins to fuse helium into carbon. Although helium fusion produces less energy than hydrogen fusion, it is also hotter, so the outer layers of the sun will expand and release a portion of the outer atmosphere into space.

When the process of turning to new elements ends, the mass of the Sun will decrease slightly, and the outer layers will extend to the current orbit of the Earth or Mars.

Satisfactory answer can't be in the 2008-11-26 The age of the sun is old, give you some scientific knowledge: the age of the sun is about 4.6 billion years, and it can continue to burn about 5 billion years The sun is the closest star to the earth, its size and brightness are medium, and it should be classified as a G1 dwarf star according to its radius and temperature. With a magnetic field and rotation, it is the largest celestial body and contains nearly 98% of the mass of the solar system.

It would take one hundred and nine Earths to fill the Sun's cross-sectional rift, and its interior could hold more than 1.3 million Earths. The visible bright surface is called the photosphere, and above the photosphere is a 5,000-kilometer-thick inner atmosphere called the chromosphere, and above the chromosopher is an extremely thin hot corona that can extend to the Earth and beyond. The activity of the sun is at its core.

The core temperature of the Sun is as high as 15 million degrees Celsius, and the pressure is more than 34 billion times that of the Earth. Nuclear fusion is happening here. Fusion causes four protons or hydrogen atoms to produce an alpha particle or helium nucleus.

The mass of the alpha particle is smaller than that of four protons, and the remaining mass is converted into energy and released to the surface of the sun, where it emits light and heat through the convection process. It takes millions of years for the energy of the sun's core to reach its surface. Every second, 700 million tons of hydrogen are converted into helium.

In the process, about five million tons of net energy are released, thus enabling the sun to shine. The age of the Sun is about 4.6 billion years, and it can continue to burn for about 5 billion years. In the final stages of its existence, the helium in the Sun will be transformed into a heavy element, and the Sun's volume will begin to expand until it engulfs the Earth.

After a 100 million year red giant phase, the Sun will suddenly collapse into a white dwarf - the final stage of all star existence. After a few more trillions of years, it will finally cool down completely. Testimonials from the major third chord:

I understand it better

Yes, all the planets in the solar system are about the same age, about 4.5-4.6 billion years ago.

Yes, in billions of years, all planets formed at the same time. So all the planets are about the same age.

The gap is still relatively large, and after the universe, the formation time of each planet is different.

Indeed, yes, and the ages of these planets are about hundreds of millions of years, and there is no way to investigate the specific time, only a general time.

1. The age of the sun before the liquid gauge is larger than that of the earth.

2. The Sun is the only star and luminous object in the solar system, and it is the central celestial body of the solar system.

3. The time when the earth accumulated from the primitive solar nebula to form a planet to the present is called the age of the earth. The current best estimate of the Earth's age is 100 million years.

The Sun is the closest star to Earth and is the central body of the solar system. The mass of the solar system is concentrated in the sun, and its strong gravitational pull controls the movement of celestial bodies such as large and small planets and comets.

It has given birth to the civilization of the earth and has always influenced the life of the earth. It is the only star whose surface structure can be studied in detail and is a huge astrophysics laboratory.

But the Sun is just an ordinary member of the 100 billion stars in the Milky Way, located near the symmetry plane of the Milky Way, about 33,000 light-years from the center of the Milky Way and about 26 light-years north of the galactic plane, on the one hand, it rotates around the galactic center at a speed of 250 kilometers per second, and on the other hand, it moves towards Vega at a speed of kilometers per second relative to the surrounding stars.

Extended Materials. The evolution of the sun.

The Sun was formed about 100 million years ago in a cloud of collapsed hydrogen molecules. The time of the Sun's formation is measured in two ways: the Sun's current age in the main sequence zone, confirmed using computer models of stellar evolution and primordial nucleosynthesis, which is about 100 million years old.

This is very consistent with the radioactive dating of the oldest material of the sun is 100 million years old. The Sun has reached middle age in the evolutionary phase of its main sequence, in which nuclear fusion is the fusion of hydrogen into helium at the core.

More than 4 million tons of matter are converted into energy in the Sun's core every second, producing neutrinos and solar radiation. At this rate, the Sun has so far converted about 100 Earth-masses of matter into energy, and the total time spent by the Sun in the main sequence is about 10 billion years.
