Overview

ℹ️

ASCC 81 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by low extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is poorly studied in the literature, with no articles listed in the last 7 years.

(*): The parallax distance estimate (~8.17 kpc) differs significantly from the median photometric distance (~0.70 kpc).
