Overview

ℹ️

Ruprecht 168 is a sparse, very loose object of low C3 quality. Its parallax locates it at a very large^* distance, below the mid-plane, affected by very high extinction. It is catalogued as an old 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 (~10.63 kpc) differs significantly from the median photometric distance (~2.63 kpc).

Relatively close Very high extinction Old

Morales et al. (2013)
Classified as morphological type 'OC2' (totally exposed cluster without correlation with ATLASGAL emission). Morphological flag: exposed cluster, without submm emission.
