Celaeno (Celeno or 16 Tauri) is a star in the constellation Taurus and a member of the Pleiades open cluster of stars. Celaeno has been called the "Lost Pleiad" by Theon the Younger.[9]
16 Tauri is a blue-white B-type subgiant with an apparent magnitude of +5.45. It is approximately 430 light years from Earth;[4] about the same distance as the Pleiades. The interstellar extinction of this star is fairly small at 0.05 magnitudes.[10] The projected rotational velocity of the equator is 185 km/s.[7] It is over four times the radius of the Sun and has a surface temperature of 12,800 K.[5][6]
Namesakes
USS Celeno (AK-76) was a United States Navy Crater class cargo ship named after the star.
