Overview

ℹ️

UBC 1366 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is rarely studied in the literature.

Relatively close Low extinction Near-solar metallicity Intermediate age
