Overview

ℹ️

Trumpler 35 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate^* distance, near the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, young cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~3.02 kpc) differs significantly from the median photometric distance (~1.58 kpc).

Note: This object shares a small percentage of members with a later reported entry. See table with shared members information.
