恒星轨道

黑洞可以推断通过跟踪运动的一组恒星轨道区域在空间看起来空。

A black hole can be inferred by tracking the movement of a group of stars that orbit a region in space which looks empty .

密度波牵涉到恒星轨道的同步化。

The wave involves the synchronization of stellar orbits .

如果接近恒星轨道旋转的行星，眼尖的观察员能发现他们在放大光存在的细微线索。

If the nearer star has orbiting planets , keen-eyed observers can spot the subtle clues of their presence in the magnified light .

行星、卫星和恒星处于轨道之中。

Planets and moons and suns are in orbit .

往南看，恒星的轨道简直成了一些很大的圆周。

Looking to the South , the paths of the stars are simply very large circles .

还有助于说明，巨大的气态外部行星如何这么近地围绕起源恒星的轨道运行。

It could also help illuminate how giant , gaseous exoplanets often come to orbit their parent stars so closely .

（太阳）系外行星通常是间接被发现的，当恒星的轨道受到附近的行星影响时，能探测到恒星的光发生变化。

Exoplanets are generally discovered indirectly by detecting changes in the light coming from a star as its orbit is affected by nearby planets .

目前存在着数千个可能的行星候选者，科学家希望能从这些候选者中确认，还有几百个运行在其它恒星周围轨道上的行星。

Several thousand possible planet candidates exist , of which scientists expect to be able to confirm several hundred more planets in orbit around other stars .

同我们太阳系的巨形气态行星不同，炽热的木星具有更靠近恒星的轨道。西恩·雷蒙德说。

Unlike gas giants in our solar system , hot Jupiters have orbits that swing tightly around their stars , says Sean Raymond , study co-author and astrophysicist at the University of Colorado in Boulder .

所以从原则上来说，你们可以决定任何，恒星在轨道中的速度，轨道的半径以及，当然，二元体系的周期。

So , in principle , you can determine for each one of those stars the velocity in orbit , the radius of their orbit and , of course , the period of the binary system .

近日点是最接近母恒星的轨道上的点，而序号为2000BD19的小行星拥有最小的轨道，与太阳无限接近。太阳是巨大的伴有核爆炸的火球，它为人类提供了温暖和生命。

Perihelion is the point in orbit nearest the parent star , and asteroid 2000 BD19 has the smallest orbit , getting incredibly intimate with the giant , hot ball of nuclear explosions that keeps us warm and alive .

一位画家描绘出的一颗外天体绕着恒星HD209458的轨道运行。

可是，论文发表之后，巨蟹座55恒星系统的轨道特征发生了较大的改变，2008年的预测明显落伍了。

However , since the paper was published , the orbital characteristics of the system have been revised significantly , throwing off the predictions of the2008 study .

科学家周四宣布，在围绕一颗遥远恒星运行的轨道上，天文学家首次发现了一颗大小与地球相近、并且可能存在水这种生命液体的行星。

For the first time , astronomers have discovered a world nearly the size of Earth orbiting a far star where water might exist as a life-giving liquid , the scientists announced Thursday .

适合居住的地带指恒星周围的轨道空间，不会因离恒星太近而导致行星表面处于沸腾状态。或者距离太远以致所有东西都被冻结。

The habitable zone refers to the orbital space around the star that 's not so close to the star that the planets surface would boil . Or so far that everything would freeze .

开普勒69c围绕一颗类太阳恒星运转，其轨道类似于金星围绕太阳公转的轨道。

The planet Kepler 69c follows a Venus-like orbit around a sunlike star .

除了这个，还能得到半径的大小，速度以及周期，假设你在地球上，和这些恒星环绕的，轨道同处一个平面。

And out of this information you get the radius , the velocity and the period , assuming that you are on Earth in the plane of the orbit of the stars .
