Overview

ℹ️

NGC 2579 is a poorly populated, loose object of low C3 quality. Its parallax locates it at a large^* distance, near the mid-plane, affected by low extinction. It is catalogued as a young cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~6.04 kpc) differs significantly from the median photometric distance (~1.03 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.
