Sh2 - 170 is a small, rarely photographed emission nebula with an embedded cluster of stars. Sh2 - 170 is located in the constellation Cassiopeia and is about 7,500 light years away from Earth. It is a young, almost circular, highly diffused H-II region, ionized by a single main sequence O star, located near the periphery of a small dense molecular cloud. Perhaps one day Sh2 - 170 will bloom into a larger rose, once more stars are created, and the resultant photons and stellar winds have pushed the cloud away from the core.
Stewart Sharpless discovered Sh2 - 170 on the 48 inch Schmidt telescope photo plates of the Palomar Observatory.
