Overview

ℹ️

FSR 0413 is a sparse, loose object of very low C3 quality. Its parallax locates it at a close^* distance, above the mid-plane, affected by high extinction. It is catalogued as a low-mass, intermediate-age cluster (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~0.96 kpc) differs significantly from the median photometric distance (~1.80 kpc).

Note: This object shares a small percentage of members with a later reported entry. 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.

Relatively close High extinction Low mass Intermediate age
