Overview

ℹ️

VDBH 253 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is very well-studied in the literature.

(*): The parallax distance estimate (~2.66 kpc) differs significantly from the median photometric distance (~1.98 kpc).

Relatively close High extinction Massive Near-solar metallicity Intermediate age

Mass determination: invalid due to poor quality CMD. Isochrone match: worst fit.
