Color of theSun
Date: 1993 - 1999
Why is the sun its color?
Wonderful question, Brian. Have you had a course in chemistry
yet? That would help answer some of your questions. Meanwhile,
go find an electric stove and turn one of the burners on "high".
Why does the burner glow red? What does your encyclopedia say
about "spectra"? Some "why" questions can take a whole lifetime
Stars have different colors according to their surface temperatures.
Cooler stars are red to orange; hotter stars are blue to white.
The Sun's surface temp is 5770 deg. Kelvin which is why it's its color.
You may have heard about temperatures in the millions of degrees
associated with the Sun. This would have been in reference to the
solar corona, a blanket of hot ionized gas extending up to around
100,000 km above the Sun's surface. The corona is normally visible
only during total solar eclipses. Why the corona is so hot is a
mystery that solar physicists are working to solve.
