Overview

ℹ️

ASCC 1 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a very massive, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.21 kpc) differs significantly from the median photometric distance (~1.60 kpc).

Relatively close Moderate extinction Very massive Intermediate age
