<P> Earth's orbit is the trajectory along which Earth travels around the Sun . The average distance between the Earth and the Sun is 149.60 million km (92.96 million mi), and one complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi). Earth's orbit has an eccentricity of 0.0167 . </P> <P> As seen from Earth, the planet's orbital prograde motion makes the Sun appear to move with respect to other stars at a rate of about 1 ° (or a Sun or Moon diameter every 12 hours) eastward per solar day . Earth's orbital speed averages about 30 km / s (108,000 km / h; 67,000 mph), which is fast enough to cover the planet's diameter in 7 minutes and the distance to the Moon in 4 hours . </P>

One revolution of earth around the sun is called a
