When hydrogen in the core of the star is depleted, a balance no longer exists between pressure and gravity, with that the core contracts and temperature rises. This cause outer layers to cool and expand. In this late stage of the star's life cycle, it is called a giant. The sun will continue to be a main sequence for about 5 billion years, then the sun will become a giant.
What else can I help you with?
How long will Spica stay on the main sequence?
Spica is a dual star system, with the two members too close for resolution by the best telescopes. The larger, primary star is a blue-white giant, and does have the potential to end it's life as a supernova. The primary is not a main sequence star. The secondary, about 70% the size of the primary, is a main sequence star, also blue white.
Is the sun a low mass or high mass sequence star?
The sun is a low mass sequence star. It is classified as a G-type main-sequence star, which means it is in the middle of its stellar evolution and will remain stable for billions of years.
Is Vega on the main sequence?
No, Vega is a main-sequence star, meaning it is currently fusing hydrogen into helium in its core. The star is relatively young compared to our Sun, so it still has a long life ahead of it on the main sequence.
Why is Sirius not a main sequence star?
Sirius is not a single star but a binary star system consisting of a white main sequence star and a white dwarf.
How long will a star with mass the same as our sun stay on the main sequence?
A star with a mass similar to that of our Sun will typically remain on the main sequence for about 10 billion years. During this phase, it fuses hydrogen into helium in its core, a process that provides stable energy output. The Sun is currently about 4.6 billion years old, meaning it has roughly 5.4 billion years left in its main sequence phase before it evolves into a red giant.
Is Proxima Centauri a main-sequence star?
Yes, Proxima Centauri is a main-sequence star and will remain so for about another four trillion years.

No, Vega is a main-sequence star, meaning it is currently fusing hydrogen into helium in its core. The star is relatively young compared to our Sun, so it still has a long life ahead of it on the main sequence.
How long does an average star spend as a hydrogen- burning main sequence star?
Ten billion years
Is a red giant star considered to be a main sequence star?
No. Red giants are not on the main sequence.
Does a red main sequence star have fusion?
A red main sequence star would be a red dwarf or a branch red giant. To be on the main sequence, you have to have hydrogen nuclear fusion.
Main sequence star distance from earth?
The sun is a main sequence star, so 1 AU.
What is a stabilized star?
Main-Sequence star
What category does a star belong in Main sequence star white dwarf red giant neutron star?
None of those is a main sequence star.
Why is Sirius not a main sequence star?
Sirius is not a single star but a binary star system consisting of a white main sequence star and a white dwarf.
