The double cluster in the constellation Perseus, normally known by its Greek designation transliterated. chi Persei (NGC 884, on the right) and h Persei (NGC 869, left) are about 7000 light-years away and less than 100 light-years apart. Although open clusters are quite common, this pair is exceptional due to the large number of young bright O and B stars in each, and their closeness.
