The cluster contains several young stars and is part of the Milky Way galaxy. The cluster is notable for its relatively high concentration of stars, which are mostly of similar age and composition. Observations of NGC_2137 can provide insights into stellar evolution and the dynamics of star clusters, making it an interesting target for both amateur and professional astronomers.
