Overview

ℹ️

BDSB 63 is a sparse, loose object of very low C3 quality. Its parallax locates it at a moderate distance, near the mid-plane. No fundamental parameter values are available for this object. It is rarely studied in the literature, with no articles listed in the last 23 years.

Note: This is very likely a unique object, which shares a small percentage of members with at least one previously reported entry. See table with shared members information.

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=0.8) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

No fundamental parameters

Classified as cluster candidate (IRCC).
