Overview
ℹ️
Collinder 461 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate 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 metallicity parameter (see Parameters). It is very well-studied in the literature.

Note: This object contains blue stragglers according to at least one source.

Note: This object shares a moderate percentage of members with 2 later reported entries. See table with shared members information.
