Overview

ℹ️

UBC 1511 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a large^* distance, near the mid-plane, affected by moderate 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 metallicity parameters (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~5.37 kpc) differs significantly from the median photometric distance (~4.09 kpc).
