Overview

ℹ️

ASCC 104 is a sparse, very loose object of low C3 quality. Its parallax locates it at a very close^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a young cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~0.41 kpc) differs significantly from the median photometric distance (~0.80 kpc).
