Overview

ℹ️

Teutsch 23 is a rich, moderately dense object of high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the distance, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.

Note: This object shares a moderate percentage of members with at least one entry reported in the same catalogue. See table with shared members information.

Relatively close Moderate extinction Near-solar metallicity Very young
