Earth lies at an average distance of 149.60 million kilometers (92.957 million miles) from the Sun and a complete orbit occurs every 365.256 days (1 sidereal year), during which time Earth travels 940 million kilometers (584 million miles).Earth's orbit has an eccentricity of 0.0167.arth's orbital speed averages about 30 km/s (67,000 mph), which is fast enough to cover the planet's diameter in seven minutes and the distance to the Moon in four hours.
