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]
