Overview

ℹ️

Collinder 89 is a poorly populated, loose object of intermediate C3 quality. Its parallax locates it at a relatively close^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~1.92 kpc) differs significantly from the median photometric distance (~0.80 kpc).

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