Description

=MsoNormalNGC 7380 is a young open cluster in Cepheus.  It was discovered by Caroline Herschel in 1787 and included by William Herschel in catalog as H VIII.77. The nebula is known as Sh2-142 in the 1959 Sharpless catalog of H-alpha regions.  It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. The NGC 7380 complex is located 8500 light years away, in the Perseus Arm of the Milky Way.  The cluster spans ~20 light-years (6 pc) with an elongated shape and an extended tail.  Age estimates range from 4 to 11.9 million years. At the center of the cluster lies DH Cephei, a close, double-lined spectroscopic binary system consisting of two massive O-type stars. This pair are the primary ionizing source for the surrounding H II region, and are driving out the surrounding gas and dust while triggering star formation in the neighboring region. Of the variable stars that have been identified in the cluster, 14 have been identified as pre-main sequence stars while 17 are main sequence stars that are primarily B-type variable.  is a young open cluster in Cepheus.  It was discovered by Caroline Herschel in 1787 and included by William Herschel in catalog as H VIII.77.
