The Fate of the Sun
Someday, the hydrogen in the Sun will run out. A long time from now. Our

The Sun is small compared to some stars. Later it will blow away the
outside parts. Then we will see a white dwarf.
Most stars end as white dwarfs. We look at stars that have already
changed. This tells us about our Sun.
