地球公转

The moon spins axisin the same amount of time it takes to orbit Earth.

月球自转周期与绕地球公转周期相等。

The volume dividing 1 day is the earth´s revolution.

除以1 日的体积就是地球公转。

Right now, the Moon´s rotation rate, and the time it takes to orbit Earth are the same.

现在，月球的自转速度与绕地球公转速度是一样的。

Half of the days of the earth revolution multiplies half of the earth´s revolution is the revolution of the sun.

地球公转日子的一半乘以地球公转的一半，就是对太阳的公转。

The tilt of the earth´s axis, not the shape of its orbit, is what is responsible for the seasons.

形成季节的主要因素不是地球公转轨道的形状，而是地球自转轴的倾斜。
