Overview

ℹ️

Collinder 333 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by high extinction. It is catalogued as a very metal-poor, intermediate-age cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~2.59 kpc) differs significantly from the median photometric distance (~1.05 kpc).

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