Overview

ℹ️

MWSC 4316 is a poorly populated, moderately dense object of very low C3 quality. Its parallax locates it at a close^* distance, well above the mid-plane, affected by low extinction. It is catalogued as an old cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~0.91 kpc) differs significantly from the median photometric distance (~1.91 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 Low extinction Old
