Multiple star system in the constellation Taurus
7 Tauri is amultiple star in the northernconstellation ofTaurus . It has a combinedapparent visual magnitude of 5.95,[ 10] Bortle scale , it is faintly visible from suburban skies at night. Measurements made with theGaia spacecraft show an annualparallax shift ofmas light years from the Sun.
7 Tauri is a binary star with two nearly equal components about″ stellar classification of A7V.[ 4] spectroscopic binary . In the past, these stars had been treated as a single system, but they are now known to have differentproper motions and somewhat different distances.[ 4]
