Overview

ℹ️

Collinder 365 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~2.67 kpc) differs significantly from the median photometric distance (~0.94 kpc).

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