Overview

ℹ️

SAI 94 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, old 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.
