Overview

ℹ️

CWNU 266 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, 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 (~4.12 kpc) differs significantly from the median photometric distance (~3.02 kpc).
