Arjuna asteroid : ウィキペディア英語版 | Arjuna asteroid The Arjuna asteroids are a class of near-Earth asteroids (NEOs) whose orbits are very Earth-like in character, having low inclination, orbital periods close to one Earth 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. ==Possible Arjunas==
