Overview
ℹ️
NGC 3293 is a very rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by low extinction. It is catalogued as a massive, near-solar metallicity, very young cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is very well-studied in the literature.
Relatively close Low extinction Massive Near-solar metallicity Very young

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

Cavallo et al. (2024)
Gold sample.
