The New General Catalogue of Nebulae and Clusters of Stars (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae.
This is a list of open clusters located in the Milky Way. An open cluster is an association of up to a few thousand stars that all formed from the same giant molecular cloud . There are over 1,000 known open clusters in the Milky Way galaxy, but the actual total may be up to ten times higher. [ 1 ]
NGC 869 (also known as h Persei) is an open cluster located 7460 light years away in the constellation of Perseus. [2] The cluster is about 14 million years old. [2] It is the westernmost of the Double Cluster with NGC 884.
NGC 7789 (also known as Caroline's Rose, [4] Caroline's Haystack, [5] or the White Rose Cluster) is an open cluster in Cassiopeia that was discovered by Caroline Herschel in 1783. Her brother William Herschel included it in his catalog as H VI.30.
NGC 2129 is an open cluster in the constellation Gemini. It has an angular distance of 2.5 arcminutes and is approximately 2.2 ± 0.2 kpc (~7,200 light years) from the Sun inside the Local spiral arm. [3] At that distance, the angular size of the cluster corresponds to a diameter of about 10.4 light years.

NGC 1502 (also known as the Golden Harp Cluster [6]) is a young [7] open cluster of approximately 60 [3] stars in the constellation Camelopardalis, discovered by William Herschel on November 3, 1787. [8] It has a visual magnitude of 6.0 and thus is dimly visible to the naked eye. [3]
