Overview

ℹ️

OC 0499 is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a relatively close distance, below the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, young cluster (see Parameters). It is rarely studied in the literature.

⚠️ 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.
