Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi) [1] in a counterclockwise direction as viewed from above the Northern Hemisphere. One complete orbit takes 365.249 days (1 sidereal year ), during which time Earth has traveled 940 million km (584 million mi). [2] See more Earth's orbit is an ellipse with the Earth-Sun barycenter as one focus and a current eccentricity of 0.0167.
