Overview

ℹ️

CWNU 3184 is a moderately populated, very loose object of intermediate C3 quality. Its parallax locates it at a very large^* distance, well above the mid-plane, affected by high extinction. It is catalogued as an old cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported in the literature.

(*): The parallax distance estimate (~16.16 kpc) differs significantly from the median photometric distance (~7.24 kpc).

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

Very distant High extinction Old Contains BSS
