<P> At an obliquity of zero , the two axes point in the same direction ; i.e. , the rotational axis is perpendicular to the orbital plane . Earth 's obliquity oscillates between 22.1 and 24.5 degrees on a 41,000 - year cycle ; the earth 's mean obliquity is currently 23 ° 26 ′ 12.9 '' ( or 23.43693 ° ) and decreasing . </P>
