Our Sun is a star that the
Earth orbits. It is a main sequence star, which means it is a middle
aged star. The Sun is alive as long as it has a supply of hydrogen to
transform into helium. Once the hydrogen is depleted, the Sun will
expand and die, leaving a planetary nebula and the Sun's core. The
planetary nebula eventually disperse into space, leaving a white dwarf
star. The dwarf star will cool and die.
