11 Tauri is a blue subgiant star that can be located in the constellation of Taurus. 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 Tauri has alternative name(s), 11 Tauri.
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 Tauri, the location is 03h 40m 46.30 and +25 d 19 ` 46.3 .
11 Tauri has a spectral type of A2IV. This means the star is (A) blue coloured (IV) subgiant. 11 Tauri lies at a distance of 522.70 light years away from our Sun and our planet Earth or to put it another way, 160.04 parsecs away from the Sun.
11 Tauri has an apparent magnitude of 6.11 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 11 Tauri has an absolute magnitude of 0.09 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
