Theoretical upper size limit for a star
Webb12 apr. 2010 · I've recently learned that the biggest known star is VY Canis majoris. It is staggeringly vast. The radius is between 1800-2100x that of the sun. The volume is … WebbThe upper limit is a bit more difficult to estimate, but I believe it’s about 260 solar masses. In the early days of the universe, some of the first stars were of these massive types; they lived and died very quickly, ending their lives in a “Pair instability” supernova.
