Overview

ℹ️

COIN-Gaia 33 is a poorly populated, dense object of high C3 quality. Its parallax locates it at a large distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age and metallicity parameters (see Parameters). It is moderately studied in the literature.

Very distant Moderate extinction Near-solar metallicity Intermediate age
