The Question

(Submitted January 08, 1999)

Is the Sun one of the hottest stars in space?

The Answer

No, the Sun is pretty middle of the road in terms of both size and temperature. The hottest stars are blue-white in color, and have surface temperatures of greater than 50,000 degrees Kelvin. The coolest are red and have surface temperatures of less than 4000 degrees Kelvin. The Sun is yellow and has a surface temperature of about 6000 degrees Kelvin. All stars are much hotter at their centers, however.

Thanks for your questions
