12 Virginis is a blue less luminour star that can be located in the constellation of Virgo. 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. 12 Virginis has alternative name(s), 12 Virginis.

Location of 12 Virginis

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 12 Virginis, the location is 12h 13m 25.99 and +10 d 15 ` 44.5 .

Physical Properties/View of 12 Virginis

12 Virginis has a spectral type of A2m. This means the star is (A) blue coloured 12 Virginis lies at a distance of 161.63 light years away from our Sun and our planet Earth or to put it another way, 49.36 parsecs away from the Sun.

12 Virginis has an apparent magnitude of 5.85 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 12 Virginis has an absolute magnitude of 2.37 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 stars temperature has been calculated at between 7500 and 10000 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.
