Overview

ℹ️

Gulliver 4 is a rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, old cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It is well-studied in the literature.

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

Relatively close Moderate extinction Near-solar metallicity Old Contains BSS
