Overview

ℹ️

NGC 3330 is a rich, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, above the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age, metallicity, and mass parameters (see Parameters). It is very well-studied in the literature.

Relatively close Low extinction Near-solar metallicity Intermediate age

Palma et al. (2025)
Classified as optical pair P550, along with UBC_496.

Almeida et al. (2025)
Mass determination: intermediate fit. Isochrone match: good fit. Silver sample.

Cavallo et al. (2024)
Gold sample.

Hunt & Reffert (2024)
Classified as open cluster. CMD classes: 0.98 (50th percentile), true positive (human-assigned).

Richer et al. (2021)
The expected number of WDs is 2.6, 0 WD candidates found, and 0 WD candidates found in the wide search.
