Lunar 100 – Object 80
Lunar 100 object 80 represents the Orientale Basin, the Moon’s best‑preserved multi‑ring impact basin with three concentric mountain rings and a mare‑filled center. It is included in the Lunar 100 because its pristine structure, immense scale, and textbook ring morphology make it the ultimate example of a multi‑ring basin. A scientifically rich feature illustrating large‑scale crustal deformation and basin formation.
