Overview
ℹī¸
Teutsch 124 is a poorly populated, very loose object of high C3 quality. Its parallax locates it at a very large* distance, below the mid-plane, affected by very high extinction. It is catalogued as a massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~13.37 kpc) differs significantly from the median photometric distance (~4.05 kpc).

Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
