The Sun

Some stats about our nearest star:

150 million km from Earth
light takes 8½ minutes to travel from Sun to Earth
surface temperature about 6000^oC
core temperature about 15,000,000^oC
main process is fusion of hydrogen nuclei to helium nuclei
estimated age of our sun is 5 billion years
estimated lifespan is 10 billion years
radiation from the sun includes a range of wavelengths from the entire electromagnet spectrum including cosmic rays

Hertzsprung-Russell diagram

This is a plot of absolute magnitude (actual brightness) of a star against the surface temperature of the star. When data from a number of known stars is plotted it shows the main sequence clearly as a cluster as well as separate clsuters for dwarf stars and giants.
