While blue giant stars have a surface temperature of at least 10,000 Kelvin, compared to say a yellow dwarf star like our Sun at about 6,000K, another type of star called blue supergiants (class I) are even more extreme, with a surface temperature of between 10,000–50,000K and luminosities of 10,000 to a million times brighter than the Sun. This star has about 12% the mass of the Sun, and about 14% the size of the Sun – about 200,000 km across, which is only a little larger than Jupiter.
