NGC 1624, also known as Sh 2-212 [3] in the Sharpless catalog, is a very young open cluster in the constellation Perseus inside an emission nebula. It was discovered by German-British astronomer William Herschel in 1790. [4] Together with Sh 2-211, this nebula is part of the Tribble Nebulae. [5] NGC 1624 is about 20,000 ly (6,000 pc) from Earth, and latest estimates give it an age of less than 4 million years. [2] Its apparent magnitude is 11.8, [1] and apparent diameter is about 3.0 arc minutes. [4] Its celestial location is right ascension (α) 04h 40m 36.0s and declination (δ) +50° 27′ 42″. [1] It is potentially an area of massive star formation. [6]

According to Robert Trumpler's classification of open clusters, this cluster contains fewer than 50 stars (letter p) with a high concentration (I) and whose magnitudes are distributed over an average interval (number 2). The letter n at the end (I2pn) means that the cluster is inside a nebula.
