Is the Sun Unusual?

The Copernican Principle has been with us for centuries. It broadly states that "we are typical" but increasingly we are beginning to question this doctrine. One famous push back is the Rare Earth hypothesis, but testing this idea will take generations. What about our Sun? Surely here we should have a better understanding as to whether our star is typical or not. Join us as we discuss why the Sun might be more special than Copernicus ever imagined.
