Overview

ℹ️

Collinder 332 is a rich, very dense object of very high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, young cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is well-studied in the literature.

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