Overview

ℹ️

Koposov 62 is a sparse, very loose object of high C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, old cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~5.81 kpc) differs significantly from the median photometric distance (~2.80 kpc).

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