<P> Earth currently has an axial tilt of about 23.4 ° . This value remains about the same relative to a stationary orbital plane throughout the cycles of axial precession . But the ecliptic ( i.e. , Earth 's orbit ) moves due to planetary perturbations , and the obliquity of the ecliptic is not a fixed quantity . At present , it is decreasing at a rate of about 47 '' per century ( see details in Short term below ) . </P>
