Notes119 Tauri is a supergiant star with a diameter estimated at nearly six hundred times that of the Sun, and calculated to possess some 66,000 times the Sun's luminosity. This is a semiregular pulsating variable, for which changing temperatures within the star drive consequent changes in its brightness over irregular periods of months or years.

The blue star to the east (left) of red 119 Tauri is 120 Tauri, also extremely distant, though actually a little closer to the Sun than the red supergiant. The fainter red star to the west (right) is DV Tauri which, though far fainter than the other two stars, is in fact the nearer of the three. Based on their parallax measurements, all three of these stars lie more than a thousand light years from the Solar System. Imagery provided by Aladin sky atlas
