Overview

ℹ️

Trumpler 14 is a very rich, very dense object of high C3 quality. Its parallax locates it at a moderate distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the absorption, age, and metallicity parameters (see Parameters). It is very well-studied in the literature.

Note: This object shares a very small percentage of members with 2 later reported entries. See table with shared members information.

Relatively close Moderate extinction Near-solar metallicity Very young
