Overview

ℹ️

NGC 2224 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by high extinction. It is catalogued as a very young cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 8 years.

(*): The parallax distance estimate (~4.37 kpc) differs significantly from the median photometric distance (~2.42 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.

Relatively close High extinction Very young
