Overview

ℹ️

MWSC 4409 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, well above the mid-plane, affected by moderate extinction. It is catalogued as a massive, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.67 kpc) differs significantly from the median photometric distance (~2.74 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 Intermediate age
