Overview

ℹ️

ASCC 52 is a poorly populated, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~2.64 kpc) differs significantly from the median photometric distance (~1.71 kpc).

Relatively close Moderate extinction Massive Near-solar metallicity Intermediate age
