WebThe axial tilt is defined as the angle between the direction of the positive pole and the normal to the orbital plane. The angles for Earth, Uranus, and Venus are approximately 23°, 97°, and 177° respectively. There are two standard methods of specifying a planet's tilt. One way is based on the planet's north pole, defined in relation to the ... WebApr 8, 2016 · One particular wobble in Earth's rotation has perplexed scientists since observations began in 1899. Every six to 14 years, the spin axis wobbles about 20 to 60 inches (0.5 to 1.5 meters) either east or west of its general direction of drift. From space, air, and on the ground, NASA studies Earth and the ways it is changin…
