Overview

ℹ️

Teutsch 31 is a poorly populated, moderately dense object of low C3 quality. Its parallax locates it at a large distance, near the mid-plane, affected by moderate extinction. It is catalogued as an intermediate-age cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is poorly studied in the literature.
