Overview

ℹ️

ASCC 74 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by low extinction. It is catalogued as a low-mass, intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~5.23 kpc) differs significantly from the median photometric distance (~0.55 kpc).
