NGC 18 is a double star system located in the constellation of Pegasus. [1] It was first recorded by Herman Schultz on 15 October 1866. It was looked for but not found by Édouard Stephan on 2 October 1882.

NGC 18 is a Double Star in the Pegasus constellation. NGC 18 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its B magnitude of 14, NGC 18 is visible with the help of a telescope having an aperture of 14 inches (350mm) or more.

Messier 18 or M18, also designated NGC 6613 and sometimes known as the Black Swan Cluster, is an open cluster of stars in the constellation Sagittarius. It was discovered by Charles Messier in 1764 and included in his list of comet-like objects. [8]
