When did the sun die and does the sun die? Why?

The Sun is a yellow dwarf, and the lifespan of a yellow dwarf is roughly 10 billion years, and the Sun is currently about 5 billion years old. As the sun ages, its luminosity increases steadily. Within about 5 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.

Since helium combustion produces more energy than hydrogen combustion, the outer layers of the Sun will expand and release a portion of the outer atmosphere into space. When the process of switching to new fuels ends, the mass of the Sun will decrease slightly, and the outer layers will extend to the current orbit of the Earth or Mars (at which point the two planets will be farther away from the Sun due to the decrease in the mass of the Sun). Since the growth of the sun's energy is not commensurate with the increase in radius, the temperature on the surface of the Sun will be lower than it is now, turning into a red giant.

After billions of years from this red giant, the helium fuel will also be depleted. Like the first consumption of hydrogen fuel, the core of the sun contracts again and the internal temperature rises. For very large stars, this collapse leads to the fusion of carbon.

However, since the Sun is not massive enough to produce carbon fusion, it will become a white dwarf. As the internal temperature and luminosity decrease, it eventually becomes a black dwarf that does not emit light.

The life span of the Sun is about 10 billion years (this is just an estimate), and the Sun has been around for 5 billion years now.

It died because of the depletion of internal nuclear fuel.

The sun is not a living thing, so you shouldn't be able to ask that.

5 billion years should be dead, it doesn't make sense not to die, it's the same as human beings.

When the Sun dies, it becomes a white dwarf or a black hole. The Sun is a yellow dwarf star with a lifespan of about 10 billion years, and at the end of its lifespan, all the hydrogen in the Sun will be depleted, and the Sun's core will collapse, causing the temperature to rise and the outer layers to expand, a process that will continue until the Sun begins to fuse helium into carbon. When the process of turning to new elements ends, the mass of the Sun will decrease slightly, and the outer layers will extend into the orbit of the Earth or Mars.

It first briefly erupts into a red giant, then shrinks and cools down sharply, gradually losing its temperature and becoming a white dwarf.

Red Giant Profile: It is a shorter period of instability that a star undergoes when it burns to the late stages. The reason why it is called a red giant is because of its red color and its huge size.

Aldebaran in Taurus and Arcturus in the constellation Pasture are red giants, and Betelgeuse in Orion is a red supergiant.

White dwarf profile: It is a star with low spike luminosity, high density and high temperature. Because of its white color and relatively small size, it is named the white dwarf, which is a star that has been brought to the end of its evolution, mainly composed of carbon, and covered with a layer of hydrogen and helium.

Sun Profile: It is the central celestial body of the solar system, occupying.

The sun used to be the first to come out and everything died 10 billion years later.

When the sun dies, you are already dead, and it's not your business.

The helium fuel will run out, and the sun will die.
