Hyades cluster. The three δ Tauri stars form a triangle at the top, with δ3 at the top, δ1 on the right, and δ2 on the left of the base.

The Bayer designation Delta Tauri (δ Tau, δ Tauri) is shared by three star systems in the constellation Taurus. They are all members of the Hyades star cluster.

Because they are close to the ecliptic, these stars can be occulted by the Moon and, very rarely, by planets.[1]
