Overview
ℹī¸
VDBH 144 is a rich, very dense object of high C3 quality. Its parallax locates it at a very large* distance, well below the mid-plane, affected by moderate extinction. It is catalogued as a massive, metal-poor, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~15.24 kpc) differs significantly from the median photometric distance (~9.64 kpc).
