Overview

ℹ️

CWNU 106 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a relatively close^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, old cluster, but with a large variance across recent sources for the age and metallicity parameters (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 (~1.70 kpc) differs significantly from the median photometric distance (~2.44 kpc).

Note: This object contains blue stragglers according to at least one source.

Relatively close Moderate extinction Near-solar metallicity Old Contains BSS
