[QUOTE="mfb, post: 5499824, member: 405866"] So you are at star number 1 of more than a billion? Check the publications for uncertainties. For the sun, the definition of "radius" itself is challenging, as it does not have a solid surface. The relative uncertainty on the mass of sun is dominated by the uncertainty on the gravitational constant, and highly correlated with the uncertainty on the mass of all other astronomical objects.
