The Sun is a typical yellow main sequence star - its mass, size, surface temperature and chemical composition lie roughly midway between the extremes exhibited by other stars. The closest star to our planet, light still takes 8.3 minutes to traverse the roughly 93 million miles between the sun and the earth.
