NGC 1220 is a young compact open cluster in the constellation Perseus. It was discovered by John Herschel in 1831. [5]

The cluster is located at l = 143.04°, b = −3.96° in the galactic coordinate system, and is 120 parsecs above the galactic plane. [1] [2] It is approximately 6m 42s east and 10′ 12″ south from the nearest visible star, γ Persei. [3]

NGC 1220 consists of approximately 26 stars with spectral types between A0 and B9, although the majority fall between A5 and B5. [2]
