When the sun dies what kind of star will it be?
It will first become a red giant, then turn into a white dwarf and in billions and billions of years it will become a black dwarf.
Does a star that has no fuel but glows faintly is a black dwarf?
A star that has burned out and no longer has fuel to sustain nuclear fusion in its core is called a white dwarf, not a black dwarf. A white dwarf is the remnant core of a low to medium mass star after its outer layers have been ejected. Over time, a white dwarf will cool down and eventually become a black dwarf, but this process takes billions of years.
Is a white Dwarf a cool star?
No. A White Dwarf is still very hot. Although over billions of years it will get cooler until it has no more residual heat. At that point it will be called a black dwarf. See related questions.
Is a black dwarf a white dwarf that has stopped glowing?
Yes, a black dwarf is essentially a white dwarf that has cooled down and no longer emits significant light or heat. After a white dwarf exhausts its remaining thermal energy over billions of years, it becomes a black dwarf, making it effectively invisible to the naked eye. However, as of now, no black dwarfs are believed to exist in the universe, as the universe is not old enough for any white dwarfs to have cooled to this stage.
What remains after a low-mass or medium-mass star dies?
After a low-mass or medium-mass star dies, it will typically leave behind a remnant called a white dwarf. A white dwarf is a dense, Earth-sized core made primarily of carbon and oxygen. It gradually cools and fades over billions of years.
How long does it take for a white dwarf to cool?
It is estimated to take at least several hundred trillion years.
How long do white dwarfs shine before they cool completely?
White dwarfs shine for billions of years before they cool completely. As they cool, they become dimmer and eventually fade into darkness, becoming black dwarfs. However, the process of a white dwarf cooling into a black dwarf takes trillions of years.
When the sun dies what kind of star will it be?
It will first become a red giant, then turn into a white dwarf and in billions and billions of years it will become a black dwarf.
How long will it take a white dwarf to cool and fade?
It takes several hundred trillion years of a white dwarf to cool.

What will the sun turn into when it runs out of fuel?
First a red giant, then a white dwarf and finally after billions of years a black dwarf. See related questions
How long does it take for a white dwarf to become a black dwarf?
Billions of years - longer than the life of our universe has passed from now (21st century).
Is a white Dwarf a cool star?
No. A White Dwarf is still very hot. Although over billions of years it will get cooler until it has no more residual heat. At that point it will be called a black dwarf. See related questions.
What is the lifespan of the dwarf star?
Dwarf stars can have lifespans ranging from tens of billions to trillions of years, depending on their size and type. The smallest dwarf stars, like red dwarfs, can burn for hundreds of billions of years, while larger dwarf stars, like white dwarfs, can exist for trillions of years as they slowly cool down.
Is there moor black holes than white dwarfs?
One black hole is created a week approxiametley. A white dwarf takes a GIANT amount of time, billions of years just to make one. And they have to go through the process of a medium sized star, which takes a couple billion years to go through.
Will the sun be a white dwarf for the rest of eternity?
No, the sun will eventually evolve into a red giant before shedding its outer layers and becoming a white dwarf. The white dwarf stage marks the end of its evolution, where it will slowly cool down over billions of years.
What is the relationship of giant white dwarf and black dwarf?
A white dwarf star is a star that has burned off all of its helium and hydrogen fuel, but which is still hot. After it cools off (which would theoretically take hundreds of billions of years), it would become a black dwarf.
