The sun has burned out half of its hydrogen fuel


The sun has burned out half of its hydrogen fuel. In a billion years from now, the sun will get so hot that the oceans on earth will begin to evaporate and the earth will be scorching hot. In five billion years from now, the sun will turn to a white dwarf, a stage in the life of a star where it expands to many times it's original size. It will suck up Mercury, Venus and possibly even the Earth. A white dwarf can burn for trillions of years. As the hydrogen fuel has been exhausted, other sources of fuel formed from nuclear fusion will be used: helium, carbon, iron, etc. With time, however, the sun will eventually burn out and explode in a giant supernova and that will be the end of our beloved star.
