What is Theta 1 Tauri

θ¹ Tauri belongs to the Hyades, the closest open cluster to Earth and the true stellar family of the Bull. With θ² it forms a naked-eye pair, two yellow giants born from the same cloud some six hundred million years ago. Together with Aldebaran —which only overlaps them in perspective— they trace the luminous face of the celestial Bull.
