Overview

ℹ️

CWNU 243 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by low 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 (~2.17 kpc) differs significantly from the median photometric distance (~1.62 kpc).

Relatively close Low extinction Near-solar metallicity Intermediate age
