The 50 Brightest Stars :

Here we present our Bright Star Catalog. It is intended for use as a source of some basic astronomical and astrophysical data for the 50 brightest stars visible from Earth. For each star, this table contains the proper name, Bayer and/or Flamsteed name, visual apparent magnitude, distance in light years, accuracy of the distance in per cent, absolute magnitude, spectral types, equatorial coordinates for J2000.0 and Hipparcos catalog number. Stars are listed in the order of decreasing visual magnitude.

RIGHT : Image of Sirius taken in X-Ray light. Sirius is the brightest star in the night sky, visible in the constellation of the Big Dog. In 1862 Sirius was discovered to be a binary star system, with a companion star. The main star, called Sirius A, is the one you see in the sky. Sirius A is about 23 times the luminosity of our Sun and 2.1 times the mass. Its companion, called Sirius B is much fainter and was the first white dwarf star discovered. Sirius B has a mass equal to that of the Sun, but its diameter is 40 to 50 times smaller. At a distance of only 8.7 light years, Sirius is the 5th nearest star system known.
