These small bodies often challenge\u0026nbsp;\u003Cbr\u003Eour expectations, revealing surprising findings that raise questions about planetary formation,\u0026nbsp;\u003Cbr\u003Eevolution, and even the origins of life. The field of planetary science seeks to address these\u0026nbsp;\u003Cbr\u003Equestions through interdisciplinary approaches, combining insights from astronomy, geology,\u0026nbsp;\u003Cbr\u003Echemistry, physics, and engineering to better understand the story of our solar system.\u003Cbr\u003EThis dissertation concerns the evolution of near-Earth asteroids, focusing on their structural,\u0026nbsp;\u003Cbr\u003Ethermophysical, and dynamical evolutions to provide a more comprehensive view of their life cycle.\u0026nbsp;\u003Cbr\u003EAsteroids exhibit a remarkable diversity of shapes, reflecting their complex evolutionary pathways.\u0026nbsp;\u003Cbr\u003EThis dissertation begins by exploring their structural condition through the development of a\u0026nbsp;\u003Cbr\u003Esemi-analytical model based on granular physics. Then, a thermophysical model is developed to\u0026nbsp;\u003Cbr\u003Ebetter characterize the thermal conditions of asteroids, a key factor giving rise to\u0026nbsp;\u003Cbr\u003Enon-gravitational perturbations on their dynamics. The final part of the dissertation focuses on\u0026nbsp;\u003Cbr\u003Eboth gravitational and non-gravitational perturbations on binary asteroid systems, by developing a\u0026nbsp;\u003Cbr\u003Ecomprehensive model that accounts for their mutual dynamics and thermophysical interactions.\u003C\/p\u003E\u003Cp\u003E\u003Cbr\u003ECommittee\u003Cbr\u003E\u2022 \u0026nbsp;Prof. Masatoshi Hirabayashi \u2013 School of Aerospace Engineering (advisor)\u003Cbr\u003E\u2022 \u0026nbsp;Prof. Christopher E.
