<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>
