Overview

ℹ️

Gulliver 7 is a rich, very dense object of very high C3 quality. Its parallax locates it at a large^* distance, below the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~8.87 kpc) differs significantly from the median photometric distance (~6.31 kpc).

Very distant Moderate extinction Massive Near-solar metallicity Intermediate age
