我们知道我们的轴的名称是23.44392911掳,但它确实像一个顶部一样旋转,这种效应被称为进动,需要25700年,这也是北极星不总是北极星的原因。这种效应只能在一个非球形的物体上实现,但因为地球在赤道处更胖,而且有地质背景,伴随着来自太阳、月亮、水星、金星、火星、木星及其卫星、土星及其卫星、天王星及其卫星、海王星及其卫星、甚至小行星和矮行星以及彗星、其他恒星和星系的引力,地轴以25700年为一个周期缓慢地漂移或摆动。这种效应在地球上不起作用球体,但它在包括地球在内的非对称物体上存在,这进一步证明了地球不是圆的。——格雷戈里
We know our axis is titled by 23.44392911掳, but it does turn around like a top, in an effect known as precession, which takes 25,700 years, and is the reason Polaris isn't always the north star.This effect can only be achieved on an object that isn't spherical, yet since Earth is fatter at its equator and has geology, and along with the gravitational pull from the Sun, Moon, Mercury, Venus, Mars, Jupiter and its moons, Saturn and its moons, Uranus and its moons, Neptune and its moons, and even the asteroids and dwarf planets along with comets, other stars and galaxies, Earth's axis slowly drifts or wobbles in a 25,700 year cycle.This effect doesn't work on a sphere, but it does on an asymmetrical object including Earth, and is further proof Earth is not round. - Gregory
