11 Librae is a white to yellow less luminour star that can be located in the constellation of Libra. 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. 11 Librae has alternative name(s), 11 Librae.

Location of 11 Librae

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 11 Librae, the location is 14h 51m 01.02 and -02 d 17 ` 55.9 .

Physical Properties/View of 11 Librae

11 Librae has a spectral type of G8.... This means the star is (G) white to yellow coloured 11 Librae lies at a distance of 216.15 light years away from our Sun and our planet Earth or to put it another way, 66.22 parsecs away from the Sun.

11 Librae has an apparent magnitude of 4.93 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 11 Librae has an absolute magnitude of 0.82 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 5200 and 6000 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.
