Overview

ℹ️

ASCC 70 is a poorly populated, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as an extremely massive, very young cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~4.99 kpc) differs significantly from the median photometric distance (~2.70 kpc).

Relatively close Moderate extinction Extremely massive Very young
