How old is our little star?
And what have you based your answer on?
It seems every time I see an astronomer or such scientist of the stars I hear a different age. Is it 4.5 billion years or what?

eeeeeeeeeeeeeeeeeeeeeeeeeeery old.
Hearsay.
The Earth is 4.5 billion years old. The sun is little over 4.6 billion years old. We know this because the sun sings, in a manner. So, we can date the sun from the time is started to sing and how it the tone changed due to his change in pressure and mass. This work was done by astronomers at Big Bear Observatory in California.

^ Great answer!!!
Here’s my single, sort of scientific, first person data point. I have a piece of terrestrial anorthosite that has been dated to 2 billion years old. So our planet and sun is older than that.
I’m going with @ScienceChick ‘s 4.6 billion years.
Hey @yesitszen!!
All the stars or our own personal star? Our personal star is about the same age as the earth, 4.5 billion years old, but it’s a relatively young star. The oldest star is about 13.8 billion years old (the age of the universe.)
OTOH, stars are being born as we speak.
THE EARTH AND THE SUN ARE ONLY 6,000 YEARS OLD!! EVERYBODY KNOWS THAT!!
