What would happen to stars when they get old?

Answer 1

In the Sun's "old age" it will have no more hydrogen atoms to convert into helium atoms, which will cause the Sun to expand into a red giant start. The Sun will increase approximately 16 million times in size, expanding beyond and swallowing Mercury, Venus, Earth and possibly Mars.

Answer 2

As the sun ages is will gradually consume the fuel in its core. When the core is depleted of hydrogen in about 5 billion years fusion will move to a shell around the core and the sun will expand into a red giant, consuming Mercury, Venus, and probably Earth. When the hydrogen shell is depleted the sun will collapse and ignite helium fusion, turning the sun into a horizontal branch star. Fusion of helium will then briefly move to a shell around a carbon-oxygen core as the sun expands once more to form an asymptotic giant. Soon afterward the sun will shed its outer layers, leaving behind a white dwarf as a remnant.

Answer 3

As stars age, they will go through different stages depending on their initial mass. Low to medium mass stars (like our Sun) will expand into red giants, shed their outer layers in a planetary nebula, and eventually become a dense white dwarf. High mass stars will undergo supernova explosions, leaving behind either a neutron star or a black hole.

Answer 4

we would all die by freezing to death like we were in one huge feezing cold freezer of freezing

Answer 5

Stars burn up and eventually die when they get old

Answer 6

it would not be as hot
