The sun is not actually burning as in a fire on earth, Burning is a chemical reaction that releases heat. The sun is a nuclear reaction. However most scientists estimate that the sun will continue to react brightly for another five billion years or so.
The sun is our local star. It is a giant fusion engine, and it is "burning" hydrogen and fusing it into helium at an enormous rate. But as long as it has fuel to drive the fusion process that is the sun's life, it will burn fuel continuously. It has been burning for about 4.5 billion years, and it has about that much more time left.
The sun has been burning for about 4.6 billion years and is currently halfway through its life cycle. It is estimated to continue burning for another 5 billion years before it exhausts its nuclear fuel and transitions into a red giant.
The Sun Is Burning was created in 1964.
The mine fire in Centralia has been burning since 1962.
