Transfer trajectories from asteroids' current orbits to Earth rendezvous are calculated in an ephemeris model (including the location of the Sun, Earth and Moon), given the initial conditions at the time of perihelion of the asteroid of interest. Due to the purely conceptual nature of the work, certain approximations are made. Firstly, a two-dimensional system where only the components of the orbit that are in the reference plane are considered, thereby neglecting the third dimension, but since Δi
