NGC 2158 is an open cluster in the constellation of Gemini. It is located southwest of open cluster Messier 35, and is believed to be about 2 billion years old.[2] The two clusters are unrelated, as NGC 2158 is around 9,000 light years further away than M35.
Once thought to be a globular cluster, NGC 2158 is now known to be an intermediate-age, metal-poor open cluster that is a member of the old thin disk population.[2]
