Overview

ℹ️

Gulliver 19 is a rich, dense object of high C3 quality. Its parallax locates it at a relatively close distance, above 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 distance, age, and metallicity parameters (see Parameters). It is moderately studied in the literature.
