Regions In Space: Trilumar Ring

The Trilumar Ring is a proposed designation for the ring-like region of space encompassing Earth, its Moon, and Mars, including interplanetary voids, orbital trajectories, potential space depots, habitats, and routes.

It spans the area around Earth (third planet), the Moon, and Mars (fourth planet), envisioned as a vital zone for human habitation, exploration, and commerce.

The term "Trilumar Ring" is a blend of Latin "tri-" (third, for Earth), "luna" (Moon), and "mar-" (from Mars), coined by @KiwiThinker on X in 2025 to name this emerging frontier.

Significant events include its introduction on X in July 2025, with discussions on its acceptance, and related proposals like "Venterra Ring" for inner regions.
