Overview

ℹ️

FSR 0304 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a low-mass, near-solar metallicity, intermediate-age cluster (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~4.16 kpc) differs significantly from the median photometric distance (~1.42 kpc).

Relatively close Moderate extinction Low mass Near-solar metallicity Intermediate age
