Overview

ℹ️

UBC 308 is a very rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high 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.

Note: This object contains blue stragglers according to at least one source.

Relatively close High extinction Near-solar metallicity Old Contains BSS
