Overview

ℹ️

Collinder 100 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.54 kpc) differs significantly from the median photometric distance (~1.56 kpc).

Relatively close Moderate extinction Intermediate age
