Overview
ℹī¸
King 10 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It is very well-studied in the literature.
Distant High extinction Massive Near-solar metallicity Young

Almeida et al. (2025)
Mass determination: invalid due to poor quality CMD. Isochrone match: worst fit.

Cavallo et al. (2024)
Gold sample.
