When the Sun is out of hydrogen- the Sun swells and becomes a red giant ,
"pulling" Mercury, Venus and Mars into it and Earth´s ice and water will be vaporized, the temperature on Earth will rise significantly - and this happens within 2,5 - 5 10 E9 years - 2,5 to 5 billion years or when sun has no hydrogen
left to burn and starts burning helium instead. When the sun runs out of helium it becomes a white dwarf, a big diamond about the size of earth and will no longer generate energy from its core... earth will be dead long before the sun becomes a white dwarf,
What else can I help you with?
When does a white dwarf die?
A white dwarf does not die in the traditional sense as it is already the end stage of a low-mass star's life cycle. However, over a very long period of time (trillions of years), a white dwarf will cool and fade away, eventually becoming a black dwarf.
How does a star turn into a white dwarf star?
A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel. Near the end of its nuclear burning stage, this type of star expels most of its outer material, creating a planetary nebula. Only the hot core of the star remains. This core becomes a very hot white dwarf, with a temperature exceeding 100,000 kelvin.
Will the sun become a white dwarf in the next 20 years?
No. It will become a white dwarf in about 7.5 billion years time.
What is a stars life cycle?
Nebulae (gas and dust) protostar (formed by immense pressure in nebulae) ^ becomes either a Brown dwarf (basicall dead :P) or a Main sequence star which becomes: A Red giant (when MSS runs out f hydrogen ) if red giant is small it becomes a white dwarf and does nothing or a planetary nebulae if it's a big one it either becomes a Neutron star or a Black hole
What will happen to earth if the sun becomes a white dwarf?
If the sun becomes a white dwarf in about 5 billion years, Earth will be engulfed by the expanding outer layers of the sun as it transitions into its white dwarf stage. Eventually, Earth will be destroyed as the white dwarf cools down and stabilizes.
What is a Star that explodes at the end of it's life known as?
A star that explodes at the end of its life is known as a supernova. This explosion can result in the star briefly outshining an entire galaxy before fading away. Supernovae play a crucial role in recycling material and spreading elements produced in the star's core into space.
Are white dwarf stars always white?
No in the life cycle of a star, a white dwarf can cool and become a black dwarf
How is white dwarf star is formed?
A white dwarf is the last stage of a low mass stars life. After a red giant is done fusing helium to carbon and oxygen, the star will collapse to a white swarf. White dwarves are usually between 15,000-6,000 kelvins.A white dwarf is formed when a small or medium-sized star runs out of fuel in its core. The star becomes a red giant and later blow off the shell into the interstellar space. The remaining core becomes a white dwarf.
What is the life expectancy of sun?
The Sun has about another 5 billion years before it becomes a red giant. Then it will become a white dwarf star, fading out as a black dwarf many billions of years from now. However, it will start to change and make life very difficult on Earth in only about one billion years.
What changes are happing during the life cycle of a white dwarf?
The white dwarf will cool down till it becomes a black dwarf. If it's part of a close binary with a main sequence, giant or supergiant, the white dwarf can gain mass from the other star. This can start fusion of carbon in the white dwarf. Other fusion reactions quickly follow, causing it to explode. This is known as type 1a supernova.
When does a white dwarf die?
A white dwarf does not die in the traditional sense as it is already the end stage of a low-mass star's life cycle. However, over a very long period of time (trillions of years), a white dwarf will cool and fade away, eventually becoming a black dwarf.
How long is the Sun's life expectancy?
It should "live" for about 5 billion years as it is, more or less. Then it will become a red giant star. Then it becomes a white dwarf. Finally it will "die" as a black dwarf.
Steps in the life of a star?
the steps in the life of a star is the yellow dwarf,red giant,white dwarf & the black dwarf.
what will the sun end its life as?
It will end Its life as a white dwarf
What is the last stage in the life cycle of earth's sun?
The core will be known as a white dwarf, while the outer regions will be known as a planetary nebula.In the end of the life cycle of the Sun, the white dwarf will release all of its remaining heat and will evolve into a cold dark mass known as a black dwarf.
What is the life story of a star?
In short... Nebula of gases --> Protostar --> Brown Dwarf --> Yellow Star --> Blue Giant --> Blue Super Giant --> Red Super Giant --> Super Nova --> Black Hole/Neutron Star/White Dwarf You should note that at any time in the life cycle of a star it may simply run out of fuel and then fade into a white dwarf. Interesting side-note if our sun should evolve into a blue giant it would eliminate all life on earth and if our sun were to run out of fuel and turn into a white dwarf it would eliminate all life on earth. Food for thought :)
The end of the sun's life will include which event?
A white dwarf cooking into a black dwarf
