131 G. Sgr - HD176704 - HIP93498

131 G. Sgr is an orange to red giant star that can be located in the constellation of Sagittarius. 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 131 G. Sgr

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 131 G. Sgr, the location is 19h 02m 27.69 and -24 d 50`47.0 .

Physical Properties/View of 131 G. Sgr

131 G. Sgr has a spectral type of K2III. This means the star is (K) orange to red coloured (III) giant. 131 G. Sgr lies at a distance of 276.18 light years away from our Sun and our planet Earth or to put it another way, 84.62 parsecs away from the Sun.

131 G. Sgr has an apparent magnitude of 5.63 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. The stars temperature has been calculated at between 3700 and 5200 based on the Class Type and lookup at Wikipedia-Stellar Classification

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.
