Overview

ℹ️

Trumpler 24 is a sparse, very loose object of low C3 quality. Its parallax locates it at a very close^* 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 age parameter (see Parameters). It is moderately studied in the literature.

(*): The parallax distance estimate (~0.42 kpc) differs significantly from the median photometric distance (~1.14 kpc).

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