Overview

ℹ️

ASCC 102 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large^* distance, well 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.

(*): The parallax distance estimate (~6.51 kpc) differs significantly from the median photometric distance (~1.50 kpc).

Relatively close Low extinction Intermediate age
