120 Tauri is a blue eruptive 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. 120 Tauri has alternative name(s), 120 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 120 Tauri, the location is 05h 33m 31.63 and +18 d 32 ` 24.8 .
120 Tauri has a spectral type of B2IV-Ve. This means the star is (B) blue coloured (IV) subgiant. 120 Tauri lies at a distance of 1,874.50 light years away from our Sun and our planet Earth or to put it another way, 574.56 parsecs away from the Sun.
120 Tauri has an apparent magnitude of 5.67 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 120 Tauri has an absolute magnitude of -3.13 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 10000 and 30000 based on the Class Type and lookup at Wikipedia-Stellar Classification
The star is a eruptive Gamma Cassiopeiae variable type which means that its size changes over time. The Variable Type is usually named after the first star of that type to be spotted. 120 Tauri brightness ranges from a magnitude of 6.000 to a magnitude of 6.000 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 1.0 days (variability).
