What is the color of Sirius star?

Answer 1

The next brightest star, as we see it, after Sirius is Canopus. The next nearest star in distance after Sirius is called Luyten 726-8. The next brightest star in Canis Major is Beta Canis Majoris or Murzim/Murzam/Al-Murzim (Arabic).

Answer 2

Sirius is actually a binary star system consisting of two stars:

A white main sequence star (spectral type A1) named Sirius A and a white dwarf companion star named Sirius B (spectral stype DA2).

The Sirius binary star system is very bright (Bayer designation αlpha CMa) partly because of the luminosity itself and because of the relative close distance to earth (only 8.6 light years away)

Answer 3

The star Sirius rises about 10 PM in this season (November 21, 2009), depending on your location. Can you find the constellation Orion?

Wait until about 11PM, and look low in the east. Follow the line of Orion's Belt back down toward the horizon, and Sirius is the very bright star. Off to the left, there is another bright star, Procyon, and further to the left is the Red Planet, Mars.

Sirius is the "Dog Star", the shoulder of the dog constellation Canis Major. In mythology, Canis Major is the hound of Orion the Hunter, following behind Orion's knee.

Answer 4

In the northern hemisphere, it is normally visible during the winter months. It is the brightest star in the night sky. It is easy to find, if you know where Orion is. The standard method of locating Sirius is to follow the direction that Orion's belt is pointing down to the left. Well below and to the left of Orion you will see Sirius when it has risen above the horizon.
