Overview

ℹ️

FSR 0816 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by high extinction. It is catalogued as a low-mass, near-solar metallicity, young cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~4.00 kpc) differs significantly from the median photometric distance (~2.10 kpc).

Note: This object shares a very small percentage of members with at least one entry reported in the same catalogue. See table with shared members information.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
