一个仿真的动画显示地球自转。
在春分时从太阳看到的地球转轴倾角（或倾角）和它相对于自转轴和轨道平面
在像地球的一个顺行平面，恒星日是短于太阳日。在时间点1，太阳和遥远的恒星都在头顶上（在相同的方向上）；在时间点2，行星转动360°，遥远的恒星右出现在头顶上，但太阳并不在头顶上（1→2 =一恒星日）；太阳要稍后，在时间点3，才会抵达头顶上（1→3 =一太阳日）。
以SI日为基础导出1962-2010年的每天长度变化。

地球自转是固体的地球绕着自己的轴转动，方向是由西向东。从天球的北极点鸟瞰，地球自转是逆时针旋转；从南极点上空看是顺时针旋转。

Earth's rotation 地球自转

（重定向自Rotation of Earth）
An animation showing the rotation of the Earth around its own axis.

Starry circles arc around the south celestial pole, seen overhead at ESO's La Silla Observatory.[22]
On a prograde planet like the Earth, the stellar day is shorter than the solar day. At time 1, the Sun and a certain distant star are both overhead. At time 2, the planet has rotated 360° and the distant star is overhead again but the Sun is not (1→2 = one stellar day). It is not until a little later, at time 3, that the Sun is overhead again (1→3 = one solar day).

Earth's rotation is the rotation of the planet Earth around its own axis. The Earth rotates from the west towards east. As viewed from North Star or polestar Polaris, the Earth turns counter-clockwise.

The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface. This point is distinct from the Earth's North Magnetic Pole. The South Pole is the other point where the Earth's axis of rotation intersects its surface, in Antarctica.
