how long does our sun live?

Answer 1

Our sun, which burns hydrogen and converts it into helium, is currently about 5 billion years old. In another 5 billion years, according to estimates, it will run out of hydrogen and begin burning the helium in its core. At that point it will swell into what is known as a red giant, expanding to several thousand times its current size, engulfing and vaporizing the four inner planets in the system, including Earth.

Answer 2

The solar isn't alive and can't die. it may run out of expendable skill. ~ it is going to run out of hydrogen that may be switched over to helium in about 5 billion years. And definite, it is going to likely be about ten billion years previous on the on the spot. ~ After that it's going to likely be some extra billion years earlier different fuels are exhausted. ~ it might want to then take the solar trillions of years to relax to the position no elementary is emitted. this may no longer ensue because in about 22 billion years from now, in accordance to some theories, the enlargement of the universe might want to tear it aside in an end call the large Rip. Even after the solar stops emitting any elementary, it is going to nevertheless exist. If there is not any huge Rip, the subsequent time of existence of our solar is taken under consideration as on the order of the time of existence of the proton, ordinary to be a minimum of 10^32 years. some effortless grand unified theories anticipate a proton existence of no more suitable than 10^40 9 years. If those theories aren't any further valid, the proton might want to decay through added complicated nuclear techniques, or through quantum gravitational techniques appropriate to a digital black hollow; in those situations, the time of existence is envisioned to be no more suitable than 10^2 hundred years. If protons do decay, the mass of our solar will shrink very slowly with time as its nuclei decay, till it loses adequate mass to develop right into a non-degenerate lump of count number, and ultimately disappear thoroughly. .

Answer 3

Scientists speculate that our Sun will live for another 5 million/billion years (I don't really know the exact value)

Answer 4

Approximately 10 Billion years. It is about half way through its life at present so will have about 5 Billion years left.

Jules, Australia.

Answer 5

It'll get about 10 billion years in all, its already had approx 5, so only 5 left

Answer 6

The sun is a mass of incandecent gas- a gigantic nuclear furnace where hydrogen is built into helium at a temperature of millions of degrees.

Answer 7

i read that it will live to 5 billions year more..

Answer 8

Until it burns up OR collapses and becomes a black hole
