Overview

ℹ️

UBC 200 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, well below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, old cluster (see Parameters). It is rarely studied in the literature.

⚠️ Warning: This is very likely a duplicate object, which shares a large percentage of members with at least one previously reported entry. See table with shared members information.
