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).
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)
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.
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.
Star numbering (or coding) varies in different star catalogs.

Very light blue. Nearly white.
Yes, Sirius is quite big while Barnard's star is small.
No. Sirius is a star.
Sirius.
Sirius is the brightest star in the night sky of earth not a galaxy
Our solar system is centred round the Sun, which is our own star, while Sirius is a nearby star that is bigger and brighter than the Sun but a lot further away. Sirius can be found near the constellation of Orion, to the lower left of it when viewed from USA or Europe. It is the brightest of all the stars, but the planets Venus and Jupiter can be brighter at times.
Sirius is actually a binary star system.Sirius A is a type A1V star so has a colour of Blue White -> BlueSirius B is a white dwarf.
Yes - Sirius is a blue-white star - the hottest type of star there is.
the dog star is called sirius and is located south west of Orion belts in the southern hemisphere
Sirius is a binary star system Sirius A and Sirius B.The distance separating Sirius A from B varies between 8.1 and 31.5 AU. (See related question).
No. The North Star is Polaris. Sirius is known as the Dog Star.
Yes, Sirius is quite big while Barnard's star is small.
It is not real. Sirius is a two-star system containing only Sirius A and Sirius B.
No. Sirius is the brightest star in Earth's night sky, but how bright a star appears is a product of its actual brightness and its distance from us. Sirius itself is actually two stars with Sirius A emitting the vast majority of the system's light. Sirius A is a fairly large star, but others are much larger.
Sirius is the brightest star in the night sky, but the brightest overall is the sun.
No. There is no such thing as an "earth-like star" as Earth is a planet, not a star. Sirius A is a star that is larger and brighter than the sun.
Sirius is not a single star but a binary star system consisting of a white main sequence star and a white dwarf.
No. There is no such thing a a cold star. Sirius consists of two stars, both of which are hotter than the average star.
