List: Top Ten Largest Known Stars
Date: As of September 2007
Source: Lowell Observatory
Base: All discovered stars measured by estimated solar diameter.
Notes: The exact order of this list is not fully complete yet due to the nature of the estimations where statistical variations in measured values exist. Nor is it completely properly defined: Double stars are sometimes treated individually, while other lists may combine them. The diameter of the Sun is 1.392 x 109 meters, or 864,900 miles.
