Overview
ℹ️
King 11 is a very rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, above the mid-plane, affected by high extinction. It is catalogued as a very massive, near-solar metallicity, old cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It is very well-studied in the literature.

Note: This object contains blue stragglers according to at least one source.

Relatively close High extinction Very massive Near-solar metallicity Old Contains BSS

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