Sirius B (Alpha Canis Majoris B) is a white star that can be located in the constellation of CanisMajor. The star can not be seen by the naked eye, you need a telescope to see it.
Alpha Canis Majoris B is the Bayer Classification for the star.
The location of the star in the galaxy is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the star is compared to the celestial equator and is expressed in degrees. For Sirius B, the location is 06h 45m 09.0 and -16 d 43` 06 .
Sirius B has a spectral type of DA2. This means the star is a white star. Sirius B lies at a distance of 8.60 light years away from our Sun and our planet Earth or to put it another way, 2.64 parsecs away from the Sun.
Sirius B has an apparent magnitude of 8.44 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.
Sirius B is an estimated 8.60 light years from our Solar System (Earth and Sun). It would take a spaceship 8.60 years travelling at the speed of light to get there. We don't have a space ship that can travel that distance or at that speed yet.
