136 Tauri - HD39357 - HIP27830

136 Tauri is a blue main sequence dwarf 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. 136 Tauri has alternative name(s), 136 Tauri.

Location of 136 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 136 Tauri, the location is 05h 53m 19.64 and +27 d 36 ` 44.2 .

Physical Properties/View of 136 Tauri

136 Tauri has a spectral type of A0V. This means the star is (A) blue coloured (V) main sequence (dwarf star). 136 Tauri lies at a distance of 437.80 light years away from our Sun and our planet Earth or to put it another way, 133.98 parsecs away from the Sun.

136 Tauri has an apparent magnitude of 4.56 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 136 Tauri has an absolute magnitude of -1.08 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 9500 Kelvin. (Based on the b-v value of 0 and the lookup on SDSS.)

136 Tauri Radius has been calculated as being 5.67 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 3,944,129.66. km.

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.
