NGC 7160 - Open Cluster in Cepheus
|
NGC 7160 is an open star cluster that lies approximately 2,500 light years in the constellation of Cepheus. It was discovered by William Herschel in 1789. It is a relatively young cluster (i.e., 11-19 million years old). The cluster lies within the Cepheus Bubble, an expanding shell that was created by an earlier supernova. The shell is approximately 390 light years in diameter.
