11 Comae Berenices is a white to yellow giant star that can be located in the constellation of ComaBerenices. 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 Comae Berenices has alternative name(s), 11 Comae Berenices. 11 Comae Berenices has at least 1 Extrasolar Panets believed to be in orbit around the star.

Location of 11 Comae Berenices

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 Comae Berenices, the location is 12h 20m 43.09 and +17 d 47 ` 33.6 .

Physical Properties/View of 11 Comae Berenices

11 Comae Berenices has a spectral type of G8III. This means the star is (G) white to yellow coloured (III) giant. 11 Comae Berenices lies at a distance of 360.80 light years away from our Sun and our planet Earth or to put it another way, 110.37 parsecs away from the Sun.

11 Comae Berenices has an apparent magnitude of 4.72 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 11 Comae Berenices has an absolute magnitude of -0.50 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
