Overview

ℹ️

Collinder 350 is a rich, very dense object of very high C3 quality. Its parallax locates it at a very close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is very well-studied in the literature.

Very close Moderate extinction Near-solar metallicity Intermediate age
