Overview

ℹ️

Collinder 213 is a moderately populated, very loose object of high C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by low extinction. It is catalogued as a metal-rich, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~2.40 kpc) differs significantly from the median photometric distance (~1.46 kpc).

Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
