Overview

ℹ️

Czernik 17 is a poorly populated, loose object of high C3 quality. Its parallax locates it at a large^* distance, well above the mid-plane, affected by moderate extinction. It is catalogued as a metal-rich, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is poorly studied in the literature.

(*): The parallax distance estimate (~7.05 kpc) differs significantly from the median photometric distance (~4.90 kpc).
