The Sun Life Cycles
I’m not sure if everyone knows but suns, just like people and animals, have life cycles. But unlike humans and animals, it takes billions of years to get to the next stage.
Our sun is an average star and scientists estimate that in 4-5 billion years our sun will collapse inwards and then expand rapidly into a red giant and will swallow Mercury, Venus, and most likely Earth. In another 100,000,00 billion years the sun will collapse into a planetary nebula and then collapse inwards into a white dwarf.
