Overview

ℹ️

HSC 545 is a sparse, very dense object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by high extinction. It is catalogued as an intermediate-age cluster (see Parameters). It was recently reported in the literature.

⚠️ Warning: This is very 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 (~3.55 kpc) differs significantly from the median photometric distance (~1.97 kpc).

Relatively close High extinction Intermediate age
