Not only that, the Moon orbits the Earth on an ellipse.

不仅如此，月球绕地球公转轨道是椭圆。

As the planet orbits the star, it makes a big circle (or ellipse) .

当行星围绕恒星运行时，它会成一个大圆(或椭圆)。

Weighing all the possibilities, the computer spits out the potential area of impact in the form of a landing ellipse.

权衡过所有可能性，计算出一个可能接触区域，一个椭圆着区。

In 1976, the landing ellipse for the Mars Viking Lander was 62 x 174 miles, nearly the area of New Jersey.

1976 年海盗号登火星登椭圆为62 x 174 英哩， 幾乎和新澤西州面積相當。

Remember too that the Moon's orbit around the Earth is an ellipse.

同样要记住是，月亮绕地球公转轨道是个椭圆。

As Kepler showed, the earth's orbit is an ellipse, with the sun at one of the two focal points.

就像开普勒曾指出，地球轨道是个椭圆，相对以太阳为中心绕话有两个焦点。

The Earth orbits the Sun on an ellipse, so think of that as the average distance of the Earth from the Sun.

地球绕太阳公转轨道是椭圆，所以可以把它看作是地球到太阳平均距离。

Now, Newton predicted that the orbit of Mercury was an oval, or as scientists like to say " an ellipse."

牛顿预测水星轨道是椭圆，或者用科学家惯用词，“椭圆”。

Unlike an ellipse, there's no exact geometric definition for an " oval" , but they can be constructed by joining other arcs of different radii.

与椭圆不同，卵没有确切几何定义，但它们可以通过连接其他不同半径弧构建。

In 2012, the landing ellipse for the Curiosity Lander was only 4 miles wide by 12 miles long, an area more than 200 times smaller than Viking's.

在2012年，好奇号椭圆着区仅有4英里宽，12英里长，比海盗号小两百多倍。

There's a common misconception that the Earth has seasons because it orbits the Sun on an ellipse, and so it's closer to the Sun in summer and farther in winter.

有一种常见误解，即认为地球四季产生是因为地球公转轨道是个椭圆，所以夏离太阳近，冬离太阳远。

On June 15,1977, I was one of 900 high schoolers greeted by the new president, President Jimmy Carter, on the south lawn of the White House, right there on the other side of the ellipse.

1977年6月15日，我作为900位高中生其中一个迎接新总统，总统吉米·卡特，见面会在白宫南草坪上，就在椭圆另一边。
