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 very high extinction. It is catalogued as a massive, metal-rich, very young cluster (see Parameters). It is poorly 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.
