Overview

ℹ️

FSR 0999 is a sparse, very loose object of low C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by moderate 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 (~3.17 kpc) differs significantly from the median photometric distance (~1.82 kpc).

Relatively close Moderate extinction Near-solar metallicity Intermediate age
