Brightest Star

The brightest star in the night sky - Sirius - is now putting on a nice show in the early evening hours. At northern latitudes, Sirius is often too low for observation, but now during spring the star is rising fairly early in the evening and due to its brightness it almost looks like a planet .

Most widely known as "the brightest star", Sirius is actually a binary star system consisting of the bright Sirius A and the white dwarf companion (Sirius B), but only a single point can be seen unless you happen to own a very powerful telescope.

Rising in the blue twilight hour Sirius is a beautiful sight.
