Overview

ℹ️

Collinder 132 is a moderately populated, loose object of very high C3 quality. Its parallax locates it at a close distance, below the mid-plane, affected by low extinction. It is catalogued as a low-mass, near-solar metallicity, young cluster, but with a large variance across recent sources for the absorption, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.

Close Low extinction Low mass Near-solar metallicity Young
