NGC 1502 is the name of an open star cluster in the constellation giraffe. In the center of the star cluster the double star ADS 2984 is located. Its components are approximately 18 arcsec apart. Both are unresolved pairs of hot, massive stars. Together they form the brightest star system in NGC 1502. The age of the star cluster is estimated to be about ten million years. NGC 1502 is about 3,000 light years away from us and only about six light years in diameter. NGC 1502 was discovered on 3 November 1787 by the German-British astronomer Friedrich Wilhelm Herschel.
