{{Short description|Class of near-Earth asteroids}} The '''Arjuna asteroids''' (also known as "Arjunas") are a dynamical group of asteroids in the Solar System. Arjunas are near-Earth objects (NEOs) whose orbits are very Earth-like in character, having low inclination, orbital periods close to one year, and low eccentricity. The group is named after Arjuna, a central hero in the ''Mahabharata''. The definition overlaps the definition of the Apollo, Amor, Aten and Atira groups. They constitute a dynamically cold group of small NEOs that experience repeated trappings in the 1:1 mean-motion resonance with the Earth.<ref name="Fuente-2013" /><ref name="Fuente-2015" />
