What will be the final stage in the Sun’s life cycle?
A planetary nebula is the final stage of a Sun-like star. As such, planetary nebulas allow us a glimpse into the future of our own solar system. A star like our Sun will, at the end of its life, transform into a red giant. Stars are sustained by the nuclear fusion that occurs in their core, which creates energy.
What are the stages in our Sun’s life cycle?
The Sun's lifecycle is nebula, main sequence star, red giant, white dwarf.
What is the final stage of our Sun quizlet?
What is the final stage in our sun's' life? White dwarf or black dwarf.

- White dwarf. Initial mass of the star is less than 8 times mass of the Sun. …
- Neutron star. Initial mass of the star is in between the 8 times mass of the Sun and 25 times mass of the Sun. …
- Blackhole. Initial mass of the star is greater than 25 times mass of the Sun.
What are the 7 stages of a star?
All stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.
- Giant Gas Cloud. A star originates from a large cloud of gas. …
- Protostar. …
- T-Tauri Phase. …
- Main Sequence. …
- Red Giant. …
- The Fusion of Heavier Elements. …
- Supernovae and Planetary Nebulae.
What is the remaining life of the Sun?
So our Sun is about halfway through its life. But don't worry. It still has about 5,000,000,000—five billion—years to go. When those five billion years are up, the Sun will become a red giant.
What is the final evolution stage as massive as the sun for a star quizlet?
The final stage in the evolution of a star like our Sun is a neutron star.
Which of the following best describes the end of our Sun’s life?
Which of the following best describes the end of our Sun's life? Our Sun will turn into a white dwarf and then slowly fade away.
What is the end life for a star like our Sun?
"This reveals the star's core, which by this point in the star's life is running out of fuel, eventually turning off and before finally dying." Astronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies.
What are the three end stages of stars?
Three possible end stages of stars are:
- White dwarf. Initial mass of the star is less than 8 times mass of the Sun. …
- Neutron star. Initial mass of the star is in between the 8 times mass of the Sun and 25 times mass of the Sun. …
- Blackhole. Initial mass of the star is greater than 25 times mass of the Sun.
Which is the final event that occurs when a star is forming?
A star like our Sun will become a white dwarf when it has exhausted its nuclear fuel. Near the end of its nuclear burning stage, such a star expels most of its outer material (creating a planetary nebula) until only the hot (T > 100,000 K) core remains, which then settles down to become a young white dwarf.
When the Sun reaches the end of its life cycle the expanded part will be released into space?
A red giant is a dying star in the final stages of stellar evolution. In about five billion years, our own sun will turn into a red giant, expand and engulf the inner planets — possibly even Earth.
Will our Sun go supernova?
The Sun as a red giant will then… go supernova? Actually, no—it doesn't have enough mass to explode. Instead, it will lose its outer layers and condense into a white dwarf star about the same size as our planet is now.
What is the final stage of a medium mass Sun like star?
A medium mass (Sun-like) star becomes a red giant. When its hydrogen and helium fuel is exhausted, it collapses and becomes a white dwarf.
What is the final evolution airy stage as massive as the Sun for a star?
Stage 7 – The core is hot enough for the helium to fuse to form carbon. The outer layers begin to expand, cool and shine less brightly. The expanding star is now called a Red Giant.
Which best describes the final phase in our sun’s life cycle apex?
*D. It will collapse and become a white dwarf. The correct answer is: It will collapse and become a white dwarf.
What is the third phase of the Sun?
Death of the Sun The sun is now a white dwarf, and the outer regions of it are a planetary nebula. Since it is no longer doing any nuclear fusion, the white dwarf will cool down slowly until it becomes the same temperature as the rest of the universe, just a few degrees above absolute zero.
What would be the last stage of the Sun Class 8?
e. The end stage of the sun will be white dwarf.
What happens at the end of a star’s life?
When a star like the Sun has burned all of its hydrogen fuel, it expands to become a red giant. This may be millions of kilometres across – big enough to swallow the planets Mercury and Venus. After puffing off its outer layers, the star collapses to form a very dense white dwarf.
Which is the final event that occurs when a star is forming quizlet?
Which is the final event that occurs when a star is forming? Nuclear fusion begins under high pressure.
Which of the following are stages the sun will reach in the course of its future evolution?
Ultimate Fate of our Sun: As such, when our Sun runs out of hydrogen fuel, it will expand to become a red giant, puff off its outer layers, and then settle down as a compact white dwarf star, then slowly cooling down for trillions of years.
At what stage of its evolutionary life is the sun?
At what stage of its evolutionary life is the Sun? Main sequence, middle age.
Will Earth lose the moon?
Calculations of the evolution of the Earth/Moon system tell us that with this rate of separation that in about 15 billion years the Moon will stop moving away from the Earth. Now, our Sun is expected to enter its Red Giant phase in about 6 to 7 billion years.
Will sun become a black hole?
Will the Sun become a black hole? No, it's too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole.
Which of the following best describes the end of our sun’s life?
Which of the following best describes the end of our Sun's life? Our Sun will turn into a white dwarf and then slowly fade away.
Which of the following is the correct order for the stages of evolution of the Sun?
The correct order of evolutionary stages for a solar mass star is: Main sequence, horizontal branch, asymptotic branch, white dwarf. The energy that fuels the Sun is generated: Only in its core.
What are the main layers of the Sun?
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.
When the Sun eventually enters its final phase and cools and fades at the very end of its life cycle it will become a?
This lifespan began roughly 4.6 billion years ago, and will continue for about another 4.5 – 5.5 billion years, when it will deplete its supply of hydrogen, helium, and collapse into a white dwarf.
What are the three end stages of star class 8?
