Overview

ℹ️

Dolidze 33 is a poorly populated, dense object of high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by high extinction. It is catalogued as a metal-poor, young cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~3.22 kpc) differs significantly from the median photometric distance (~2.06 kpc).

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