When the Sun runs out of fuel, it will enter the red giant phase, expanding significantly and engulfing the inner planets, possibly including Earth. After shedding its outer layers, it will leave behind a hot core known as a white dwarf, which will gradually cool and fade over billions of years. Eventually, it will become a cold, dark remnant, often referred to as a black dwarf, though this stage is theoretical as the universe is not old enough for any black dwarfs to currently exist.

What kind of stars become white dwarfs?

After a star like our Sun runs out of nuclear fuel, it will shed its outer layers and become a white dwarf. White dwarfs are created from low to medium mass stars (like the Sun) that have exhausted their nuclear fuel and undergone certain stages of stellar evolution.


What will happen if the sun will lost its fuel?

If the sun were to run out of fuel, it would eventually expand into a red giant, consuming Mercury and Venus, and possibly Earth. After this phase, it would shed its outer layers to become a planetary nebula, leaving behind its core as a white dwarf. The white dwarf would slowly cool and fade away over billions of years.


The sun will eventually use up its hydrogen fuel and become what?

The sun will eventually exhaust its hydrogen fuel and will undergo a transformation into a red giant star. This will happen in about 5 billion years. After that, it will shed its outer layers and become a white dwarf.


What will the sun turn into when it runs out of fuel or fusion does this mean the end of life on earth?

At first, the sun will soon run out of its primary fuel, hydrogen. This will cause the sun's layers to expand, becoming a red giant. This will likely happen in 5 billion years. While scientists are unsure whether the expanded the sun will engulf the Earth or not, it will likely end life on Earth nonetheless.After it runs out of all fuel, including the heavier elements, it will begin shedding its outer layers and become a planetary nebula. Life on Earth would've almost certainly ceased by then.


What will happen to the sun in 7 billion years?

First in about 5 billion years the sun will run out of fuel in its core and become a red giant as it burns fuel around its core. After that is finished 7 billion years from now the sun will finally die and become a white dwarf.

Which progression do astronomers expect our sun to follow as it runs out of fuel?

When the sun runs out of fuel it is expected to turn into a red supergiant engulfing earth. Then it is supposed to shrink into a white dwarf.


What will happen to the star Proycon when it runs out of fuel?

That would be "Procyon". Since its mass is only about 1.5 times the mass of our Sun, I would expect it to become a white dwarf.
