The earth wobbles on its axis
網頁That is the situation on a weird, wobbly world found by NASA's planet-hunting Kepler space telescope. The planet, designated Kepler-413b, precesses, or wobbles, wildly on its spin axis, much like a child's top. The tilt of the planet's spin axis can vary by as much as 30 degrees over 11 years, leading to rapid and erratic changes in seasons. 網頁But even the geographic north pole moves up to 10 meters a year as the earth wobbles on its axis due to seasonal air pressure differences across the globe, melting ice caps, and so on. Assuming that the Russians planted their flag exactly at the geographic north pole in August 2007, not once since then has it been exactly at the pole.
