137 G. Cet - HD8556 - HIP6564

137 G. Cet is a blue to white main sequence dwarf star that can be located in the constellation of Cetus. 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 137 G. Cet

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 137 G. Cet, the location is 01h 24m 20.48 and -06 d 54`52.8 .

Physical Properties/View of 137 G. Cet

137 G. Cet has a spectral type of F4V. This means the star is (F) blue to white coloured (V) main sequence (dwarf star). 137 G. Cet lies at a distance of 146.07 light years away from our Sun and our planet Earth or to put it another way, 44.76 parsecs away from the Sun.

137 G. Cet has an apparent magnitude of 5.92 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

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.
