I have read that the estimated age of our Milky Way galaxy is 13.61 billion years which is by using our current size and status of our galaxy about 59.17 Galactic years which each galactic year representing the time taken our sun to make a full rotation around the current galactic center (i.e. 230 million years).
However, since our galaxy has started with a much smaller size and evolved and also known that the age of the Earth is 4.543 billion years, I am asking if there is way to estimate how many full rotations around the galactic center Earth has done so far since its creation?
