Overview

ℹ️

HSC 1511 is a sparse, very dense object of low C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It was recently reported in the literature.

Relatively close Moderate extinction Near-solar metallicity Young

Palma et al. (2025)
Classified as tidal capture (resonant trapping pair) P29, along with HSC_1510.
