Overview
ℹī¸
IRAS 01546+6319 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a large* distance, above the mid-plane, affected by high extinction. It is catalogued as a metal-rich, very young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~5.35 kpc) differs significantly from the median photometric distance (~2.40 kpc).

Note: This object shares a very small percentage of members with a later reported entry. See table with shared members information.

⚠ī¸ Warning: the low UTI value and no obvious signs of duplication (Cdup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
