Planetary-Induced Nutation of the Earth: Direct Terms
Abstract
Small torques by the planets can alter the direction of the Earth's rotation axis in space. These direct planetary-induced nutations have been computed using a numerical technique. 62 nutation terms with periods between 0.2 and 883 yr are presented. The maximum nutation is 0.5 marcsec. Also given are planetary-induced rates and accelerations of precession and obliquity.
