Could this be achieved using a carefully designed sequence of asteroid flybys?</p> <p>In this computational physics project, we will investigate whether repeated gravitational encounters between Earth and asteroids could transfer enough energy and angular momentum to increase Earth&rsquo;s distance from the Sun by 1%. The project will combine classical mechanics, orbital dynamics, and numerical modelling.</p>
