一个天文单位是地球与太阳之间的距离。
An astronomical unit is the distance between Earth and our sun.
地球与太阳之间的距离变化并不能产生季节，但它会影响季节的长短。
So Earth's varying distance from the sun doesn't create the seasons. But it does affect the length of the seasons.
因为有水，地球有了一个与众不同的未来。地球与太阳之间的距离适中，不太远，不太正。
But the earth had an exceptional future, offered to it by water, at the right distance from the sun, not too far not the near.
由于金星离地球更近，所以它的视差角会更大。哈雷计算出，利用金星可以测量出太阳与地球之间的距离，误差为五百分之一。
As Venus was closer to the Earth, its parallax angle would be larger, and Halley worked out that by using Venus it would be possible to measure the Suns distance to 1 part in 500.
这三种不同的日食的发生跟太阳、月球和地球三者的相互变化着的位置有关，并且也决定于月球与地球之间的距离变化。
This three different solar eclipse occurred with the sun, moon and Earth all three of the mutual changes of position, and also decided on the Moon and the distance between the Earth changes.
其大小是地球的1.4倍，距其主星的距离却比水星与太阳之间的距离小了20倍之多，而公转周期也缩短至0.84天。
And with 1.4 times the size of Earth, Kepler-10b is more than 20 times closer to its star than Mercury is to the sun, and whips around the star once every 0.84 days.
那我们地球岂不是很幸运，与太阳之间的距离正当适宜。
So we Earthlings are lucky I guess that we are just the right distance away from the sun.
大地震对调节地球自身运行状态有三种影响：一。大地震使太阳与地球之间的距离(横向)发生变化。
The earthquake caused three kinds of affects to regulate the earth: Firstly it makes distance chang between the sun and the earth (horizontal).
凭借地球和太阳之间距离为基线和魔术几何定律，哥白尼运算出木星与太阳的距离是地球与太阳距离的5倍。
By using the Earth-sun distance as his baseline, Copernicus relied upon the magic of geometry to figure out that Jupiter is over 5 times the Earth's distance from the sun!
