Starting from the conditions of law of conservation of energy and angular momentum,how to deal with simple disposal of several physical equations of the planetary motion by applying the elementary mathematical equations is proposed.

从角动量和能量守恒定律出发，建立行星椭圆运动的轨道方程，导出行星运动时的各个物理量表达式，从而给出了一种以初等数学为基础的处理行星运动的简洁方法。

类耗散性可能使稳定的混沌轨道转变为"混沌类瞬态"，并最终被椭圆岛（可称为"规则类吸引子"）捕获。

It was Newton who proved mathematically that the path of a planet must be an ellipse.

Because of the ellipticity of the earth's orbit the solar radiation incident on the earth is about 7% greater in December than in June.

In 1976, the International Astronomical Union revised the definition of the AU for greater precision, defining it as that length for which the Gaussian gravitational constant takes the value 0.01720209895 when the units of measurement are the astronomical units of length, mass and time.

但实际上地球绕日的轨道不是一个圆形，而是一个椭圆形：最初天文单位的定义就是上述椭圆的半长轴的长度。1976年，国际天文学联会把一天文单位定义为一颗质量可忽略、公转轨道不受干扰而且公转周期为365.2568983日的粒子与一个质量相等约一个太阳的物体的距离。
