7 Tauri is a multiple star in the northern constellation of Taurus. It has a combined apparent visual magnitude of 5.95, so, according to the Bortle scale, it is faintly visible from suburban skies at night. Measurements made with the Gaia spacecraft show an annual parallax shift of 5.5 mas, which is equivalent to a distance of around 593 light years from the Sun.

7 Tauri is a multiple star in the northern constellation of Taurus. It has a combined apparent visual magnitude of 5.95, so, according to the Bortle scale, it is faintly visible from suburban skies at night. Measurements made with the Gaia spacecraft show an annual parallax shift of 5.5 mas, which is equivalent to a distance of around 593 light years from the Sun. 7 Tauri is a binary star with two nearly equal components about 0.7″ apart, designated as A and B. The spectrum of each star matches a stellar classification of A7V. 22″ away is a 10th-magnitude star, component C, which is itself a spectroscopic binary. In the past, these stars had been treated as a single system, but they are now known to have different proper motions and somewhat different distances.
