NGC 1193 is an open cluster in the Perseus constellation.[2] It was first observed and catalogued by astronomer William Herschel in 1786.[3] The cluster is estimated to be approximately 4.2 billion years old.[4]
NGC 1193 is usually classified as a Trumpler type II3m,[5] indicating its stellar population have a wide range of brightness, from very bright to faint stars and little star concentration in the center of the cluster. The letter 'm' on the Trumpler classification indicates a population of 50 to a 100 stars. However a study released in 2022 indicates a population of approximately 181 stars in the cluster, possibly changing the type from II3m to II3r. A photometric study of this galaxy carried out in 1988 revealed a small population of 5 blue straggler stars, a number of subgiant branch stars and red giant branch stars.
