21 Tauri, formally named Asterope ,{{cite journal

Asterope was one of the Pleiades sisters in Greek mythology. This star traditionally shared the name Sterope or Asterope with 22 Tauri, and was sometimes called Sterope I. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalogue and standardize proper names for stars. The WGSN decided to attribute proper names to individual stars rather than entire multiple systems. It approved the name Asterope for 21 Tauri on 21 August 2016 and it is now so included in the List of IAU-approved Star Names.

21 Tauri is a blue-white hued B-type main sequence star with a stellar classification of B8 V. It is a single star with around three times the mass of the Sun and is 100 million years old. The star is radiating 100 times the Sun's luminosity from its photosphere at an effective temperature of 11,041 K. It displays an infrared excess, but this is due to reflection nebula rather than a circumstellar disk.
