自转

沿着自转轴转动的球体
数学中的自转
地球的自转
月球的公转

自转,是指对象自行旋转的运动,对象会沿着一条穿过本身的轴旋转,这条轴被称为「自转轴」。一般而言,自转轴都会穿越天体的质心。

恒星和行星都会自转,小天体亦大多会自转。作为天体的集合体,星系也会自转。

如果行星自转轴在长期运动中渐渐偏离原有方向,即会产生岁差。

英语百科

Rotation 自转

A sphere rotating about an axis
Rotation of a planar figure around a point
Rotational Orbit v Spin
Relations between rotation axis, plane of orbit and axial tilt (for Earth).

A rotation is a circular movement of an object around a center (or point) of rotation . A three-dimensional object always rotates around an imaginary line called a rotation axis. If the axis passes through the body's center of mass, the body is said to rotate upon itself, or spin. A rotation about an external point, e.g. the Earth about the Sun, is called a revolution or orbital revolution, typically when it is produced by gravity.
