Overview

ℹ️

FSR 1712 is a sparse, loose object of very low C3 quality. Its parallax locates it at a relatively close^* distance, near 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 (~1.82 kpc) differs significantly from the median photometric distance (~1.14 kpc).

Note: This is very likely a unique object, which shares a small percentage of members with at least one previously reported entry. See table with shared members information.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=0.76) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
