Overview

ℹ️

Teutsch 127 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a metal-rich, very young cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It is moderately studied in the literature.

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