The Arjuna asteroids (also known as "Arjunas") are a dynamical group of asteroids of near-Earth asteroids (NEOs) whose orbits are very Earth-like in character, having low inclination, orbital periods close to one year, and low eccentricity. The class is named after Arjuna, a central hero in Hindu mythology. The definition is somewhat fuzzy and overlaps the definition of the three well-established families Apollo, Amor and Aten. They constitute a dynamically cold group of small NEOs that experience repeated trappings in the 1:1 mean-motion resonance with the Earth.[1][2]
