Overview

ℹ️

Collinder 102 is a sparse, very dense object of low C3 quality. Its parallax locates it at a relatively close^* distance, near the mid-plane, affected by low extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~1.59 kpc) differs significantly from the median photometric distance (~0.90 kpc).
