Overview

ℹ️

CWWL 2073 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~4.80 kpc) differs significantly from the median photometric distance (~3.60 kpc).

Note: This object shares a moderate percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
