Overview

ℹ️

Teutsch 198 is a poorly populated, very dense object of high C3 quality. Its parallax locates it at a large^* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~7.34 kpc) differs significantly from the median photometric distance (~5.16 kpc).

Note: This object shares a significant percentage of members with 2 later reported entries. See table with shared members information.
