NGC 24 is a spiral galaxy in the southern constellationofSculptor, about 23.8 megalight-years distant from the Milky Way.[3] It was discovered by British astronomer William Herschel in 1785, and measures some 40,000 light-years across.[7] The general shape of this galaxy is specified by its morphological classification of SA(s)c,[5] which indicates it is an unbarred spiral with no ring-like structure and moderate to loosely-wound spiral arms. This galaxy is positioned in the vicinity of the Sculptor Group, but is actually a background object that is more than three times as distant. It may form a pair with another background galaxy, NGC 45.[8]
