Overview

ℹ️

MWSC 5572 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a very large^* distance, well below 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 (~67.57 kpc) differs significantly from the median photometric distance (~1.47 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
