Astronomers predict that after the Sun exhausts its nuclear fuel and leaves the main sequence, it will expand into a red giant, engulfing the inner planets of our solar system, including Earth. Eventually, the Sun will shed its outer layers, forming a planetary nebula, leaving behind a small, dense core known as a white dwarf. The white dwarf will gradually cool and fade, marking the end of the Sun's life cycle.

How many years do scientists believe are left before the Sun runs out of hydrogen in its core and leaves the main sequence?
Scientists estimate that the Sun has about 5 billion years left before it exhausts the hydrogen in its core and leaves the main sequence. As it approaches this stage, it will gradually evolve into a red giant. This process marks a significant transition in the Sun's life cycle, ultimately leading to its transformation into a white dwarf after shedding its outer layers.
How do astronomers know that hydrogen is present in almost every star in the universe?
Astronomers use spectroscopy to analyze the light emitted by stars. By studying the absorption lines in a star's spectrum, astronomers can identify the elements present in its composition. Since hydrogen leaves a distinct signature in these absorption lines, scientists have found that hydrogen is the most abundant element in stars, including our Sun.
Will the K-type Epsilon Eridani star eventually evolve into a G-type main sequence star like the Sun?
No. A star's class on the main sequence is ultimately predetermined by its mass, so a star cannot change its position on the main sequence. Epsilon Eridani is about 82% the mass of the sun, which limits it to a lower rate of fusion and thus a lower temperature and luminosity than a G-type star like the sun. Epsilon Eridani's only change in class will come when it leaves the main sequence to become a red giant.
What stage will the Sun likely enter after the main sequence stage?
our Sun will eventually become a red giant and a white dwarf.... Once the sun finishes fusing Hydrogen into helium it will start fusing helium. It will need more pressure to do this so it will expand. But it will cool a little as it expands. It all has to do with equilibrium. Our sun will become a red giant and expand to about half way between earth's orbit and mars' orbit. This will not happen for another 5 billion years or so supposedly since as far as we can tell stars like our sun stay in the main sequence for 10 billion years give or take and our sun is about 5 billion years old or so.
How will the sun evolve after the main star?
After the Sun leaves the main sequence (By running out of fuseable hydrogen) it will become an asymptotic red giant. After that, when it runs of of all fuel, stellar winds will blow away the Sun's envelope into a protoplanetary nebula (and eventually a planetary nebula) with a white dwarf in the middle, which will slowly cool to background temperature over ten quadrillion years.

Nothing will happen to her,she leaves in may on the babys funiral roomy tells kat she took her baby but kat don't believe her, but Easter Ronny leaves and Tommy gets reunited with his mummy :)
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.
