Most observed white dwarfs have relatively high surface temperatures, between 8,000 K and 40,000 K. A white dwarf, though, spends more of its lifetime at cooler temperatures than at hotter temperatures, so we should expect that there are more cool white dwarfs than hot white dwarfs. 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 .
