Overview

ℹ️

FSR 0952 is a poorly populated, very loose object of intermediate C3 quality. Its parallax locates it at a moderate^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as an old cluster (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~4.20 kpc) differs significantly from the median photometric distance (~1.99 kpc).

Note: This object shares a large percentage of members with 2 later reported entries. 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 Moderate extinction Old
