Overview

ℹ️

CWNU 492 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a close^* distance, above the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is rarely studied in the literature.

⚠️ Warning: This is likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.

(*): The parallax distance estimate (~0.89 kpc) differs significantly from the median photometric distance (~0.68 kpc).
