Overview

ℹ️

Theia 2730 is a sparse, moderately dense object of very high C3 quality. Its parallax locates it at a moderate distance, below the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, young cluster (see Parameters). It was recently reported in the literature.

Note: This is very likely a unique object, which shares a small percentage of members with at least one previously reported entry. See table with shared members information.
