119 Tauri

It is approximately 1,800 light years from Earth, and with a colour index of +2.07 it is one of the reddest naked eye stars in the night sky.

[7] Although CE Tauri is classified as a pulsating variable, observations using the same equipment and wavelengths have not detected significant changes in the angular diameter over time.

[7] Angular diameter measurements can be combined with absolute observed fluxes to derive an accurate effective temperature, about 3,800 K for 119 Tauri.

Gaia Data Release 2 gives a distinctly larger parallax, but with even greater uncertainty and flagged as unreliable.

[7] An alternative interpretation of observations, under the assumption that CE Tauri is an asymptotic giant branch (AGB) star, give it a current mass of 8 M☉ and a luminosity of 44,000 L☉.

On the left the two tips of the bull's horns Elnath (β Tauri, 1,6 ^m , at the top, north of the ecliptic) and Tien Kuan (ζ Tauri, 2,9 ^m , at the bottom, south of the ecliptic). A little bit below and right the Red Giant 119 Tauri (4,3 ^m ).
