Overview

ℹ️

CWNU 146 is a poorly populated, loose 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 an extremely metal-poor, very young 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 (~3.43 kpc) differs significantly from the median photometric distance (~2.45 kpc).

Relatively close Moderate extinction Extremely metal-poor Very young
