107 Aquarii - HD223024 - HIP117218

107 Aquarii is a blue to white main sequence dwarf star that can be located in the constellation of Aquarius. 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. 107 Aquarii has alternative name(s), 107 Aquarii.

Location of 107 Aquarii

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 107 Aquarii, the location is 23h 46m 00.84 and -18 d 40`42.1 .

Physical Properties/View of 107 Aquarii

107 Aquarii has a spectral type of F2:V+.... This means the star is (F) blue to white coloured (V) main sequence (dwarf star). 107 Aquarii lies at a distance of 212.21 light years away from our Sun and our planet Earth or to put it another way, 65.00 parsecs away from the Sun.

107 Aquarii has an apparent magnitude of 5.28 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 107 Aquarii has an absolute magnitude of 1.21 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 7300 Kelvin. (Based on the b-v value of 0.29 and the lookup on SDSS.)

107 Aquarii Radius has been calculated as being 3.34 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 2,326,645.95. km. 107 Aquarii brightness ranges from a magnitude of 5.000 to a magnitude of 5.000 over its variable period. The smaller the magnitude, the brighter the star.

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.
