What is the common modern estimate for the radius of UY Scuti compared to our Sun?
Answer
909 times that of our Sun
Modern observations place the radius of UY Scuti at about 909 times the radius of the Sun ($R_ ext{odot}$). Historical or less precise figures suggested up to 1,700 times the Sun's radius.
