119 Tauri is a star in the constellation Taurus. It is one of the largest stars known, having a diameter 510 times that of the Sun.

119 Tauri is a M-type red supergiant with a mean apparent magnitude of +4.32. It is approximately 1920 light years from Earth. It is classified as a semiregular variable star and its brightness varies from magnitude +4.23 to +4.54 with a period of 165 days. With a colour index of +2.07, 119 Tauri has been identified as the second reddest star in the night sky to shine consistently at a naked eye brightness well above the 5th magnitude. [ [http://www.astroscience.org/abdul-ahad/ruby-star.htm "Realm of the majestic ruby star in Taurus"] , October 19, 2004.] Down to a limiting magnitude of +5, it is superseded in redness only by the Garnet Star (Mu Cephei).The star is sometimes referred to as the Ruby Star, and lies 4.6 degrees off the ecliptic. This makes it a candidate for occultations by the Moon and (extremely rarely) by one of the bright planets.The angular diameter of 119 Tauri has been measured in three colors by lunar occultation.
