Overview

ℹ️

Teutsch 28 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 high extinction. It is catalogued as a massive, 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.

Note: This object contains blue stragglers according to at least one source.

Distant High extinction Massive Near-solar metallicity Intermediate age Contains BSS
