Overview

ℹ️

HSC 1547 is a sparse, moderately dense object of low C3 quality. Its parallax locates it at a large^* distance, near the mid-plane, affected by high extinction. It is catalogued as a massive, young cluster (see Parameters). It was recently reported in the literature.

⚠️ Warning: This is likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.

(*): The parallax distance estimate (~5.01 kpc) differs significantly from the median photometric distance (~8.78 kpc).
