The earthquake also shifted the so-called figure axis of the earth, which is the axis that the earth's mass is balanced around.
地震也改变了地球的几何中轴线，中轴的周围地球的重量是平衡的。
Well, the sun rotates about its axis in 26 days, the earth in one day, and so I finally convert everything to MKS units and I find these Numbers for the rotational kinetic energy.
太阳的旋转周期是，26天，地球是一天，最后把一切转化成，米千克秒的单位，得到旋转动能的数据。
Earth is a bit closer to the sun in early January and farther away in July, although this variation has a much smaller effect than the heating and cooling caused by the tilt of Earth's axis.
