Overview

ℹ️

Saurer 5 is a sparse, very loose object of intermediate C3 quality. Its parallax locates it at a very large^* distance, above the mid-plane, affected by high extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is rarely studied in the literature.

(*): The parallax distance estimate (~13.79 kpc) differs significantly from the median photometric distance (~5.28 kpc).

Note: This object shares a significant 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.
