Orbit and characterization
''Ariane'' orbits the Sun at a distance of 2.1–2.4
AU once every 3 years and 4 months (1,219 days). Its orbit has an
eccentricity of 0.07 and an
inclination
Orbital inclination measures the tilt of an object's orbit around a celestial body. It is expressed as the angle between a Plane of reference, reference plane and the orbital plane or Axis of rotation, axis of direction of the orbiting object ...
