Overview

ℹ️

W 75 N is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane. It is catalogued as a cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 23 years.

(*): The parallax distance estimate (~4.31 kpc) differs significantly from the median photometric distance (~2.00 kpc).

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

⚠️ 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.
