NGC 1624, also known as Sh 2-212 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. Together with Sh 2-211, this nebula is part of the Tribble Nebulae.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. Its apparent magnitude is 11.8, and apparent diameter is about 3.0 arc minutes. Its celestial location is right ascension (ñ) and declination (ô) . It is potentially an area of massive star formation.
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.
