106 G. Cen - HD106922 - HIP59950

106 G. Cen is a blue main sequence dwarf star that can be located in the constellation of Centaurus. HIP is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD. The Id of the star in the Gould Star Catalogue is . Stars in the southern hemisphere are more likely to have a Gould Id than the northern hemisphere. For example, there are no Gould classified stars in Ursa Major.

Location of 106 G. Cen

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 from celestial equator. The Declination is how up or down compared to the celestial equator and is expressed in degrees. For 106 G. Cen, the location is 12h 17m 47.29 and -36 d 05`38.3 .

Physical Properties/View of 106 G. Cen

106 G. Cen has a spectral type of A0V. This means the star is (A) blue coloured (V) main sequence (dwarf star). 106 G. Cen lies at a distance of 488.27 light years away from our Sun and our planet Earth or to put it another way, 149.62 parsecs away from the Sun.

106 G. Cen has an apparent magnitude of 6.15 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 106 G. Cen has an absolute magnitude of 0.27 which is the apparent magnitude of an object if it were 32.6 light years away or 10 parsecs from Earth. 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. The star's temperature has been calculated at being about 9500 Kelvin. (Based on the b-v value of 0 and the lookup on SDSS.)

106 G. Cen Radius has been calculated as being 3.04 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 2,118,058.27. km.

Source of Information

The source of the information came from Simbad, the Hipparcos data library based at the University at Strasbourg, France. Hipparcos was a E.S.A. satellite operation launched in 1989 for four years.
