NGC-7790 is an open star cluster located in the constellation of Cassiopiea, just over 2 degrees NW of Beta Cassiopieae. NGC-7790 is a relatively young cluster, estimated to be 60 to 80 million years old, which lies 10,800 years from Earth, and as a result, its brightness has suffered an extinction of almost 1/2 magnitude due to intervening dust and gas. This cluster contains 3 Cepheid type variable stars.
