Overview

ℹ️

UBC 207 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a very close distance, below the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, very young cluster (see Parameters). It is poorly studied in the literature.

Note: This is a unique object, which shares a very small percentage of members with at least one previously reported entry. See table with shared members information.
