NGC 1624, also known as Sh2-212[3] in the Sharpless catalog, is a very young open cluster in the constellation Perseus inside an emission nebula.

[4] 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.

[4] Its celestial location is right ascension (α) 04h 40m 36.0s and declination (δ) +50° 27′ 42″.

[5] 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.
