Overview

ℹ️

Collinder 316 is a moderately populated, very dense object of very high C3 quality. Its parallax locates it at a relatively close^* distance, above the mid-plane, affected by low extinction. It is catalogued as a cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 12 years.

(*): The parallax distance estimate (~1.65 kpc) differs significantly from the median photometric distance (~1.00 kpc).

Note: This is likely a unique object, which shares a moderate percentage of members with at least one previously reported entry. See table with shared members information.
