Overview

ℹ️

CWNU 493 is a poorly populated, dense object of low C3 quality. Its parallax locates it at a relatively close^* distance, above the mid-plane, affected by high extinction. It is catalogued as a metal-rich, very young cluster (see Parameters). It is rarely studied in the literature.

⚠️ Warning: This is very 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 (~1.72 kpc) differs significantly from the median photometric distance (~2.57 kpc).
