What Kind of Star Is the Sun, What Is the Temperature of the Surface of the Sun, and How Was the Sun Formed?

The star nearest to us, the Sun, is a mature star.

It is classified as a red dwarf. In terms of spectral class, it is a G2V star.

G2 indicates its surface temperature of approximately 5,778 Kelvin.

Its absolute magnitude is +4.8, so it is of average brightness for a star.

Because the Sun is so close to Earth, it looks like the brightest star in the universe; so its apparent magnitude is –27.72.

In its core, the Sun fuses 430–600 million tons of hydrogen each second.

The formation of the Sun may have been triggered by shockwaves from one or more supernovae that are close to it.
