Overview
ℹī¸
Trumpler 27 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 (see Parameters). It is well-studied in the literature.

(*): The parallax distance estimate (~2.52 kpc) differs significantly from the median photometric distance (~1.21 kpc).

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

Morales et al. (2013)
Classified as morphological type 'OC2' (totally exposed cluster without correlation with ATLASGAL emission). Morphological flag: exposed cluster, without submm emission.
