Overview
ℹī¸
Collinder 463 is a very rich, very dense object of very high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by low extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.
Close Low extinction Massive Near-solar metallicity Intermediate age

Almeida et al. (2025)
