That means that the speed of the Moon around the Sun will vary between about 103% and 97% of the speed of the Earth around the Sun.
这就意味着月球绕行太阳的速度的改变范围是在地球绕行太阳速度的97% ~ 103%范围之间。
Since the eccentricities are small, we can assume that the orbits of the Earth around the Sun and the Moon around the Earth are both circles.
由于偏心率小，我们假定地球绕太阳的轨道和月球绕地球的轨道都是圆形。
The speed of the Earth around the Sun is about 30 times the speed of the Moon around the Earth.
地球绕行太阳的速度大约是月球绕地球的30倍。
The Moon is in orbit around the Earth at an approximate distance of 377, 000 km (234, 000 miles).
月亮所运行的轨道距离地球约为377,000公里（234,,000英里）。
In orbit around the Moon, the orbiter was about 372,335 kilometers from Earth.
环绕月球时，卫星距离地球约372,335公里。
It takes 29 days for the moon to rotate around its axis, and it also takes 29 days for the moon to orbit around the Earth.
月球自转一周需29天，围绕地球旋转一周也同样需29天。
Any user of Google Earth 5.0 can now roam around the moon without the need to update the program. Just click on the planet button in the top toolbar and select 'moon.'
