Overview
Kharchenko 3 is a poorly populated, very dense object of intermediate C3 quality. Its parallax locates it at a moderate* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a metal-poor, young cluster (see Parameters). It is poorly studied in the literature.
(*): The parallax distance estimate (~2.88 kpc) differs significantly from the median photometric distance (~2.13 kpc).
Note: This object shares a significant percentage of members with a later reported entry. See table with shared members information.
