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.
