WebEarth 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] WebIt travels around our planet once every 27.322 days in an elliptical orbit, an elongated circle. The Moon is tidally locked with Earth, which means that it spins on its axis exactly once each time it orbits our planet. Because of this, people on Earth only ever see one side of the Moon. We call this motion synchronous rotation.
