When it expands, its outer layers will … Our solar system is just over 4.5 billion years old, so the sun is slightly more than halfway through its stable lifetime. b. density; temperature. It will then start burning helium to carbon for a couple of million of years until, eventually, the helium runs out. Assuming that luminosity is caused only by fusion of the Sun's remaining hydrogen, calculate how long our star will be a red giant. *Astronomers and geologists are still attempting to reconcile this paradox. Over time, massive stars become red supergiants, and lower-mass stars like the Sun become red giants. The Sun will only spend one billion years as a red giant, as opposed to the nearly 10 billion it spent busily burning hydrogen. a) it forms much faster b)it lives a shorter time on the main sequence The Sun will run out of hydrogen fuel in its core in about 5 billion years and will have to start burning helium, forcing it to become a red giant star. 🚨 Claim your spot here. Hydrogen fusion in the shell produces more helium. Which, well, sucks. I have good news and bad news. The good news is our sun will never explode.

Living with the Stars describes the many fascinating connections between the universe and the human body, which range from the makeup of DNA and human cells, growth and aging, to stellar evolution and the beginning of the universe. Is our sun a red giant? The trouble starts in the distant future when the sun's core runs out of hydrogen fuel for nuclear fusion. In about five billion years the Sun will run out of hydrogen fuel and swell into a red giant star over a thousand times its current volume before shrinking back into a white dwarf. Sun will exhaust the hydrogen fuel in its core and start burning helium, forcing its transition into a red giant Unfortunately, before that happens, the sun will become too hot for life to survive here in 1.75 to 3.5 billion years. A high-mass star (many times more massive than the Sun) goes through a similar, but a slightly different process. Then they are red giants for a while, and then something else happens (depending on the mass of the star). This will cause all sorts of problems, especially if the sun becomes bigger in radius than the earth's orbit. As the sun evolves, it’ll expand to become a red giant star and fry our planet to a cinder. T… In 5.4 billion years from now, the sun will enter what is known as the red giant phase of its evolution. With every pulse, the Sun will shrug off layers of its outer atmosphere until all that’s left is a cold, heavy core, surrounded by a planetary nebula. Clever name, that, because the Sun will in fact become a giant red star and eventually expand beyond the Earth’s orbit. Today they know that our time is much shorter, albeit still more than one billion years.
