Overview

ℹ️

SAI 113 is a rich, very dense object of intermediate 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, intermediate-age cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is poorly studied in the literature.

Distant Moderate extinction Near-solar metallicity Intermediate age
