CI Tauri has alternative name(s) :- CI Tau.
More details on objects' alternative names can be found at Star Names .
The location of the subgiant star in the night sky 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 along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. For CI Tauri, the location is 04h 33m 52.00 and 22° 50` 30.00 .
CI Tauri has a spectral type of K4IV. This means the star is a orange to red subgiant star.
The star is believed to be about 0.00 Billion years old. To put in context, the Sun is believed to be about five billion years old and the Universe is about 13.8 billion years old.
CI Tauri has an apparent magnitude of 13.00 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 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.
