117 G. Eri is a blue to white giant star that can be located in the constellation of Eridanus. 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.
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 117 G. Eri, the location is 03h 41m 13.75 and -11 d 48`09.0 .
117 G. Eri has a spectral type of F2III. This means the star is (F) blue to white coloured (III) giant. 117 G. Eri lies at a distance of 299.78 light years away from our Sun and our planet Earth or to put it another way, 91.67 parsecs away from the Sun.
117 G. Eri has an apparent magnitude of 6.49 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 6000 and 7500 based on the Class Type and lookup at Wikipedia-Stellar Classification
