Its apparent magnitude is 4.83, making it visible to the naked eye with dark skies. 126 Tauri is a well-known binary star with the two components in an eccentric orbit of over a hundred years. The secondary, component B, has also shown radial velocity variations that indicate an unseen companion in a 4.77-day orbit. The combined spectral class is typically quoted as B3IV, occasionally B3V.2014yCat....1.2023S VizieR Online Data Catalog: Catalogue of Stellar Spectral Classifications (Skiff, 2009- ) Skiff B. A.
