Astronomy Fun Fact:

Solar diameter: 864940 miles. (109 Earth diameters)
Solar mass 4.376 x 10³⁰ lb (333,000 Earth masses)
Solar surface temperature: 10,400 F. Sunspots are on average 1500 F cooler.

Sunspots are only "dark" in comparison to the rest of the solar surface. An isolated sunspot would be bright as an electric arc.
