Overview

ℹ️

Collinder 417 is a sparse, very dense object of intermediate C3 quality. Its parallax locates it at a relatively close^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~1.79 kpc) differs significantly from the median photometric distance (~1.02 kpc).

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