Overview

ℹ️

DBSB 144 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a very massive, near-solar metallicity, young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~2.29 kpc) differs significantly from the median photometric distance (~3.83 kpc).

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