所以，轨道总体上说是椭圆的。

So, orbits in general are ellipses.

youdao

但是，一般的解决方法，还是需要一个椭圆轨道。

But the general solutions call for a elliptical orbit.

youdao

总功是负的，所以是椭圆轨道。

It is negative; it is an ellipse.

youdao

最近，月球到达了离地最近的椭圆轨道点上。

It has reached the point where this oval orbit is nearest to the Earth.

youdao

总是负的，好吧，以后的课，我们会讲椭圆轨道。

It's always negative. Okay, later in the course we will cover elliptical orbits.

youdao

所以，这是一个椭圆轨道，这是P，这是。

So here is an ellipse, A here is P and here is A.

youdao

月球椭圆型的轨道意味着它到地球的距离是变化着的。

The Moon's elliptical orbit means its distance from the Earth is not constant.

youdao

彗星像行星一样围绕太阳运转，但其轨道是长长的椭圆形状。

Comets move around the sun like planets, but in a long oval pattern.

youdao

月球绕地球运行的轨道不是浑圆的，而是椭圆的。

The moon doesn't describe a circle round the earth, but rather an ellipse .

youdao

地球的轨道与其说是圆形，还不如说是椭圆形。

The earth's orbit is more like an oval than a circle.

youdao

一方面，他是椭圆的，但是其他行星的轨道都是接近圆的。

One, it's elliptical, but the others are nearly circular.

youdao

冥王星的轨道是椭圆形的。

Pluto has an elliptic orbit.

youdao

月亮可能是按照一个椭圆形的轨道围绕我们的地球飞行。

The Moon may be flying around our Earth in an oval-shaped.

youdao

地球的轨道是椭圆形的。

Theorbit of the earth is elliptical.

youdao

第一定律（轨道定律）：所有行星都沿各自的椭圆轨道运动，太阳在该椭圆的一个焦点上。

The orbit of every planet is an ellipse with the Sun at a focus.

youdao

彗星象行星一样绕太阳运转，然而其轨道呈狭长的椭圆形。

Comets move around the sun like planets, but in long oval course.

彗星象行星一样绕太阳运转，然而其轨道呈狭长的椭圆形。

Comets move around the sun like planets, but in long oval course.
