Orbit of Venus
Venus has an orbit with a semi-major axis of 0.723 au (108,200,000 km; 67,200,000 mi), and an eccentricity of 0.007. The low eccentricity and comparatively small size of its orbit give Venus the least range in distance between perihelion and aphelion of the planets: 1.46 million km. The planet orbits the Sun once every 225 days and travels 4.54 au (679,000,000 km; 422,000,000 mi) in doing so, giving an average orbital speed of 35 km/s (78,000 mph).
