Overview

ℹ️

UBC 635 is a rich, loose object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 6 years.

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