Overview

ℹ️

MWSC 5154 is a sparse, moderately dense object of low C3 quality. Its parallax locates it at a close distance, well above the mid-plane, affected by low extinction. It is catalogued as a low-mass, old cluster (see Parameters). It is poorly studied 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.
