Overview

ℹ️

Pismis 1 is a rich, very dense object of high C3 quality. Its parallax locates it at a large 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 absorption, age, and metallicity parameters (see Parameters). It is very well-studied in the literature.

Very distant Moderate extinction Near-solar metallicity Young
