Overview

ℹ️

NGC 2202 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by low extinction. It is catalogued as a low-mass, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the distance and absorption parameters (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~3.27 kpc) differs significantly from the median photometric distance (~0.90 kpc).

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Close Low extinction Low mass Near-solar metallicity Intermediate age
