NGC 1276 is an optical [2] [3] double star system [1] [8] [9] [10] located in the constellation Perseus. [1] [8] [10] The system was discovered by astronomer John Dreyer [1] [10] [11] on December 12, 1876. [1] [11] The pair consists of two 15th magnitude stars [1] [4] known as Pul -3 270349 and Pul -3 270357 that are unrelated as they lie at different distances from each other. [4] [2] [3] Pul -3 270349 lies at a distance of 1,134.5587 parsecs (3,700.436 ly) [2] and Pul -3 270357 lies at a distance of 1,774.6229 parsecs (5,788.046 ly). [3]
The two stars are about the same size and luminosity as the Sun. [5]
