What is the last phase of the sun?

All stars die, and eventually — in about 5 billion years — our sun will, too. Once its supply of hydrogen is exhausted, the final, dramatic stages of its life will unfold, as our host star expands to become a red giant and then tears its body to pieces to condense into a white dwarf.

What are the stages of the sun in order?

The Sun’s lifecycle is nebula, main sequence star, red giant, white dwarf.

What will be the final end state of the sun?

white dwarf
The Sun is destined to perish as a white dwarf. But, before that happens, it will evolve into a red giant, engulfing Mercury and Venus in the process. At the same time, it will blow away Earth’s atmosphere and boil its oceans, making the planet uninhabitable.

Which stage is the Sun in?

main sequence star
The Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf. The white dwarf star will run out of nuclear fuel and slowly cool down over many billions of years.

What stage is the Sun in 2021?

The sun has enough nuclear fuel to stay much as it is now for another 5 billion years. After that, it will swell to become a red giant. Eventually, it will shed its outer layers, and the remaining core will collapse to become a white dwarf.

What are the 3 stages of the Sun?

The Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf. The white dwarf star will run out of nuclear fuel and slowly cool down over many billions of years.

What are the 7 stages of the Sun?

Formation of Stars Like the Sun

• STAGE 1: AN INTERSTELLAR CLOUD.
• STAGE 2: A COLLAPSING CLOUD FRAGMENT.
• STAGE 3: FRAGMENTATION CEASES.
• STAGE 4: A PROTOSTAR.
• STAGE 5: PROTOSTELLAR EVOLUTION.
• STAGE 6: A NEWBORN STAR.
• STAGE 7: THE MAIN SEQUENCE AT LAST.

What stage is the Sun currently in?

What are the end stages of stars?

Three and stages of stars are white dwarf, neutron star and a black hole.

What stage is the Sun now?

The Sun is currently a main sequence star and will remain so for another 4-5 billion years. It will then expand and cool to become a red giant, after which it will shrink and heat up again to become a white dwarf.

How old is sun now 2021?

Our Sun is 4,500,000,000 years old.

What are the Sun layers?

The inner layers are the Core, Radiative Zone and Convection Zone. The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona. IRIS will focus its investigation on the Chromosphere and Transition Region.

How long will the Sun Live after the final phase?

Final Phase and Death: Once it reaches the Red-Giant-Branch (RGB) phase, the Sun will haves approximately 120 million years of active life left. But much will happen in this amount of time.

What is the main sequence of the Sun’s Life?

The Main Sequence Stage Like most stars in our universe, the Sun is on the main sequence stage of its life. This means nuclear fusion reactions in its core fused hydrogen into helium. However, this process cannot last forever since there is a finite amount of hydrogen in the core of the Sun. Currently it has more than 72\% hydrogen.

What will happen to the Sun when it dies?

This will begin in approximately 6.4 billion years at which point the Sun will exit the main sequence stage of its life. With its hydrogen exhausted in the core, its inner helium ash that has built up there will become unstable and collapse under its own weight.

What kind of star is the Sun?

The sun is a middle-aged star. The sun is made of about 74\% hydrogen and 24\% helium. (Cain, 2008) 1st: Research the life cycles of all stars. 2nd: Determine what star the sun is and the path it is on.
