Overview

ℹ️

Cepheus C is a sparse, very loose object of very low C3 quality. Its parallax locates it at a large^* distance, above the mid-plane. It is catalogued as a cluster (see Parameters). It is rarely studied in the literature, with no articles listed in the last 23 years.

(*): The parallax distance estimate (~5.12 kpc) differs significantly from the median photometric distance (~0.75 kpc).

⚠️ Warning: the low UTI value and no obvious signs of duplication (C_dup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.

Bica et al. (2003)
Classified as infrared cluster (IRC).

Lada & Lada (2003)
Embedded cluster within ∼2 Kpc of the Sun.
