Overview

ℹ️

Ruprecht 6 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large distance, below the mid-plane. It is catalogued as a near-solar metallicity, old cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 7 years.

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.

Very distant Near-solar metallicity Old
