What will the fate of our sun be like?

In about 5.5 billion years the Sun will run out of hydrogen and begin expanding as it burns helium. It will swap from being a yellow giant to a red giant, expanding beyond the orbit of Mars and vaporizing Earth—including the atoms that make-up you.

What is the ultimate fate of the sun quizlet?

Gas ejected from a low-mass star in the final stage of its life. The ultimate fate of our Sun is to____. become a white dwarf that will slowly cool with time.

What is the ultimate fate of the cores of the most massive stars?

Instead, its core will collapse, leading to a runaway fusion reaction that blows the outer portions of the star apart in a supernova explosion, all while the interior collapses down to either a neutron star or a black hole.

What is the fate of a star about the mass of our sun?

About 75\% of the mass of the star is ejected into space in the supernova. The fate of the left-over core depends on its mass. If the left-over core is about 1.4 to 5 times the mass of our Sun, it will collapse into a neutron star. If the core is larger, it will collapse into a black hole.

What is the ultimate fate of a star whose mass is 1 solar mass?

Stage 5 – A star of one solar mass remains in main sequence for about 10 billion years, until all of the hydrogen has fused to form helium. Stage 6 – The helium core now starts to contract further and reactions begin to occur in a shell around the core.

What are the three ultimate fates of stars?

Our four stars illustrate the four possible fates of the stars: black holes, neutron stars, white dwarfs, and red dwarfs. The Sun will end its life as a hot-but-faint white dwarf, an object no larger than the earth, and like a dying ember in a campfire it will gradually cool off and fade into blackness.

What will happen when the sun burns out?

The sun burning out is the inevitable fate. We dont have to worry though: is not going to happen for about 5 billion years. The sun is currently burning hydrogen. When its supply of hydrogen depletes, it will burn its supply of helium that it has been saving up for a couple billion years.

Will the Sun ever burn out?

Yes, the sun will some day burn out, but that will not be for billions of years! All glaciers on earth will melt and eventually all water will be gone and Earth will turn into a planet sort of similar to Venus and everything will melt as it gets hotter and hotter.

What happens when the Sun dies?

In about 5 billion years from now, the sun will begin to die. As the Sun grows old, it will expand. As the core runs out of hydrogen and then helium, the core will contract and the outer layers will expand, cool, and become less bright. It will become a red giant star.

How long before the Sun dies?

The sun will die in about 5 billion years, but it’ll only take about a billion or so years before Earth becomes uninhabitable, or at the very least very uncomfortable.
