Overview

ℹ️

VVVX-Obasi 18 is a sparse, loose object of low C3 quality. Its parallax locates it at a moderate distance, above the mid-plane. No fundamental parameter values are available for this object. It was recently reported in the literature.

⚠️ 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.

No fundamental parameters
