Editing Arjuna asteroid (section)

{{Short description|Class of near-Earth asteroids}}
The '''Arjuna asteroids''' (also known as "Arjunas") are a dynamical [[List of minor-planet groups|group]] of [[asteroid]]s in the [[Solar System]]. Arjunas are [[near-Earth object]]s (NEOs) whose [[orbit]]s are very [[Earth]]-like in character, having low [[inclination]], [[orbital period]]s close to one year, and low [[eccentricity (orbit)|eccentricity]]. The group is named after [[Arjuna]], a central hero in Hindu historic script [[Mahabharata]]. The definition is somewhat more relevant and overlaps the definition of the four well-established [[Apollo asteroid|Apollo]], [[Amor asteroid|Amor]], [[Aten asteroid|Aten]] and [[Atira asteroid|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" />
