Overview

ℹ️

SAI 137 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a large^* distance, below the mid-plane, affected by high extinction. It is catalogued as an intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~6.08 kpc) differs significantly from the median photometric distance (~1.73 kpc).

Relatively close High extinction Intermediate age
