它在軸上擺動歐美十大證明地球不是圓的在歐美十大證明地球不是圓的中排名第4名。

我們知道我們的軸的名稱是23.44392911擄，但它確實像一個頂部一樣旋轉，這種效應被稱為進動，需要25700年，這也是北極星不總是北極星的原因。這種效應只能在一個非球形的物體上實現，但因為地球在赤道處更胖，而且有地質背景，伴隨著來自太陽、月亮、水星、金星、火星、木星及其衛星、土星及其衛星、天王星及其衛星、海王星及其衛星、甚至小行星和矮行星以及彗星、其他恒星和星系的引力，地軸以25700年為一個周期緩慢地漂移或擺動。這種效應在地球上不起作用球體，但它在包括地球在內的非對稱物體上存在，這進一步證明了地球不是圓的。——格雷戈里

We know our axis is titled by 23.44392911擄, 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
