Overview

ℹ️

ASCC 7 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a large^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a massive, young cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~6.51 kpc) differs significantly from the median photometric distance (~2.00 kpc).

Relatively close Moderate extinction Massive Young
