Pronunciation: /trɪˈluːmɑːr rɪŋ/
Etymology: A blend of Latin "tri-" (third, referencing Earth as the third planet from the Sun), "luna" (Moon), and "mar-" (from Mars, the fourth planet). The term captures the sequential and interconnected nature of these celestial bodies, forming a conceptual ring or toroidal band in the solar system through their orbital paths.
Definition: A proposed designation for the ring-like region of space encompassing Earth, its Moon, and Mars, including the interplanetary voids, orbital trajectories, potential space depots, habitats on surfaces and in orbit, as well as commuter and long-haul cargo routes; envisioned as a vital zone for future human habitation, exploration, and commerce linking the third and fourth planets.
Origin: The term "Trilumar Ring" was first coined by KiwiThinker in 2025 during speculative discussions on space exploration architectures, drawing from the need for a unified name for this emerging frontier of human activity.
Example: "As humanity expands outward, the Trilumar Ring will serve as the primary corridor for missions, with depots facilitating efficient transfers between Earth, the Moon, and Mars."
Related terms: Cislunar space, cismartian space, interplanetary space, Moon-to-Mars architecture, orbital torus, inner solar system.
