Lonely, Gianni Sabato - Yellow (Original Mix)

Like the Sun, medium-sized stars are, "yellow", because they have a medium temperature. Their higher temperature causes them, to burn their fuel faster. This means, they will not live as long, only about 10 billion years, or so. Near the end of their lives, these medium-sized stars, swell up, becoming very large. (sounds like most celebrities), When this happens to the Sun, it will grow large enough, to engulf even the Earth. Eventually they shrink again, leaving behind most of their gas. This gas forms, a beautiful cloud around the star, called a Planetary Nebula.
the sun, is only about 5 billion years old. It still has another 5 billion years or so, before it will expand, and turn into a planetary nebula. or less depending on the rate of loss of stellar mass, but that is another story for another time as, standardz, hahahahaha, :) #edio
