Overview

ℹ️

SAI 120 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by very high extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 16 years.

(*): The parallax distance estimate (~3.81 kpc) differs significantly from the median photometric distance (~2.55 kpc).
