Overview
Loden 309 is a poorly populated, very loose 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 a near-solar metallicity, intermediate-age cluster (see Parameters). It is moderately studied in the literature.
(*): The parallax distance estimate (~1.96 kpc) differs significantly from the median photometric distance (~0.80 kpc).
