Overview

ℹ️

OC 0211 is a poorly populated, very loose object of intermediate C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It is rarely studied in the literature.

Note: This is a unique object, which shares a very small percentage of members with at least one previously reported entry. See table with shared members information.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=0.96) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
