Therefor it can't be 4.5 billion years old as that is even younger than the stated estimated age of earth. This would require the earth to have wondered into the solar system from elsewhere and taken up orbit. I'm pretty sure that the estimated age for the earth is something like 4.8 billion years. :-) just wanted to let you know :-)
it isn't even important. i just am nit-picky to a degree when it comes to numbered dates in astronomy. it really ground my ears to hear an amazing podcast host throw out a number for an astronomical date that was millions of years off and showed ignorance on their part in terms of astronomy(though astronomy can easily be wrong about the dating :-) i still like seeing people have the "right" numbers :-)

Stars have cycles of birth, childhood, middle age, old age and death, much like people. The difference, of course, is in the number of years involved. The sun is roughly 4.5 billion years old now and will keep increasing in temperature, brightness and size in the ages ahead. The sun's radius has grown by 6 percent in its lifetime, and it has enough hydrogen fuel to last it another 5 billion years, which puts it just short of middle age.
Estimates are just that, Conifer. At the number of years we are talking about....a few million years here or there only matter to the sources that reference it. But I've found numerous references to the 4.5 billion year age estimate.....for what thats worth.
