Overview

ℹ️

UBC 415 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a close distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the absorption and age parameters (see Parameters). It is moderately studied in the literature.

Close Moderate extinction Near-solar metallicity Very young

Liu et al. (2025)
Classified as primordial binary cluster 144 along with FSR_0569, and as primordial binary cluster 182 along with HSC_1082, and of multiple system 22 along with CWNU_77, FSR_0569 and HSC_1082.

Palma et al. (2025)
Part of multiple system G85, along with HSC_1052, HSC_1082, CWNU_77 and FSR_0569.
