NGC 1444 is a small open cluster of stars in the northern constellation of Perseus, about 2-14° to the northwest of 43 Persei.[3] It has an angular diameter of arcminutes and a brightness of 6.60 in visual magnitude. The cluster has sixty members of seventh magnitude or fainter, and is better appreciated in larger telescopes.[3] NGC 1444 was discovered on 18 December 1788 by the German-British astronomer William Herschel.[4][5][6] It is located at a distance of 4,200 light-years from the Sun and is about 7.1[1] million years old. The cluster has a physical core radius of 1.73 ± 0.42 ly and a tidal radius of 17.4 ± 4.2 ly.[1] The most prominent member is the triple star system Σ446, with a magnitude 6.7 primary.[7] The cluster is a member of the Camelopardalis OB1 association.[7]
