Overview

ℹ️

Trumpler 11 is a rich, very dense object of very high C3 quality. Its parallax locates it at a moderate distance, below 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 and metallicity parameters (see Parameters). It is very well-studied in the literature.

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