The search for NEOs as potential candidates for use in space missions to Venus and Mars

In this work, we analyzed the orbits of over 35000 (as of 2024) near-Earth objects (NEOs) focusing on the potential for successive approaches to all pairs of planets: Earth, Venus, and Mars during the period from 2020 to 2120. We selected 120 candidates for fast transfers (within 180 days) between the following planet pairs: Earth-Mars, Earth-Venus, Mars-Earth, Mars-Venus, Venus-Earth, and Venus-Mars. We found only two candidates for double transfers (consecutive approaches involving three planets), and 10 candidates for multiple transfers, where an asteroid exhibits several consecutive paired approaches to planets within a century.
