Overview

ℹ️

VDBH 47 is a rich, very dense object of high C3 quality. Its parallax locates it at a close^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 12 years.

(*): The parallax distance estimate (~0.71 kpc) differs significantly from the median photometric distance (~1.65 kpc).

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