Overview

ℹ️

FSR 0784 is a sparse, moderately dense object of high C3 quality. Its parallax locates it at a relatively close^* distance, above the mid-plane, affected by extremely high extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 16 years.

⚠️ Warning: This is likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.

(*): The parallax distance estimate (~1.68 kpc) differs significantly from the median photometric distance (~4.76 kpc).

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=0.2) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
