Overview

ℹ️

UBC 418 is a moderately populated, moderately dense 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 a near-solar metallicity, young cluster, but with a large variance across recent sources for the metallicity and mass parameters (see Parameters). It is poorly studied in the literature.

Note: This object shares a very small percentage of members with 3 later reported entries. See table with shared members information.
