Gosh, the difference is remarkable! Sirius is actually a binary star! Two stars that are in close orbit and look like one light source from the earth (without a telescope). Sirius, the Dog star, is the brightest star in the sky (the sun aside), and it is is a white main sequence star and a small companion white dwarf. The sun is a medium sized main sequence star. Use the links and check the Wikipedia articles out. Cool pics await!
