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° eastward per solar day (or a Sun or Moon diameter every 12 hours). Earth's orbital speed distance to the Moon in 4 hours. From a vantage point above the north pole of either the Sun … Visa mer Earth's orbit is an ellipse with the Earth-Sun barycenter as one focus and a current eccentricity of 0.0167.
