Overview

ℹ️

Collinder 471 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a very close^* distance, above the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~0.34 kpc) differs significantly from the median photometric distance (~2.00 kpc).

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