Overview
ℹ️
NGC 146 is a moderately populated, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, young cluster (see Parameters). It is very well-studied in the literature.

Note: This object shares a small percentage of members with 2 later reported entries. See table with shared members information.

Relatively close Moderate extinction Near-solar metallicity Young
