Overview

ℹ️

Loden 821 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, very young cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~5.28 kpc) differs significantly from the median photometric distance (~2.80 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 Moderate extinction Massive Near-solar metallicity Very young
