In other words, spectral type increases to the left on the H-R diagram. Its surface temperature of 9,900 degrees F results in a yellowish light, just as Planck's equations predict. It has surface temperatures around 25.000 degrees Celsius / 45.000 degrees Fahrenheit. Sirius is a binary star. That means it's a much hotter star than our sun; its surface temperature is about 17,000 degrees . Sirius is highly visible in the Northern Hemisphere's winter night sky, because the star has a high luminosity, or intrinsic brightness, relative to other stars, and because it's relatively close .
