Overview
ℹ️
Negueruela 1 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is very well-studied in the literature.

Note: This object shares a large percentage of members with at least one entry reported in the same catalogue. See table with shared members information.
