The increasing luminosity of the Sun threatens Earth's habitability in ~600 million years. This paper presents the first detailed mathematical and physical analysis of a viable solution to migrate Earth to 1.3 AU using 500 m to 1 km asteroides under optimal launch windows (170° ≥ Venus ≤ 190° and 165° ≥ Mars ≤ 195°). We model the N-body interactions (Earth, Sun, Venus, Mars, Moon, and asteroids) to determine gravitational perturbations, orbital stability, and the Moon's eccentricity impact (~3.23 × 10⁻⁸ per flyby). Results show that Earth's migration is technically feasible with minimal impact on Venus, Mars, and the Moon, and an estimated timeframe of 5,332 years using 100 asteroids per window. While 600 million years may seem distant, preparing for such challenges today is essential for the long-term survival of humanity. This work lays the theoretical foundation for a scalable solution to the Stellar Death Clock problem.
