other six hail from the Oort Cloud more than 5, 000 times farther out.───其他六个产生于又远出5000多倍的奥尔特星云。

The Oort Cloud is thought to extend about 1 light year from the Sun.───欧特云团距太阳1光年距离。

Perhaps when this planet is at the far end of its path around the Sun, it reaches the inner edge of the Oort cloud.───当这颗行星运行到其公转轨道的远日点时，刚好就到达奥尔特彗星云的内缘。

The theory was that Nemesis crashed through the Oort cloud every 27 million years and sent a shower of comets in our direction.───该理论认为涅墨西斯星球每隔2700万年会穿过奥尔特云向地球发射一大批彗星。

Occasionally, a comet is deflected from the Oort cloud to orbit the Sun in a long, elliptical path.───偶而，彗星转离欧特云，绕太阳以长椭圆路径作轨道运行。

Lissauer and his colleagues have long suspected a planet-size object, sometimes called Tyche, could be hiding in the Oort Cloud.───李索尔和他的同事很久前就怀疑有一个行星大小的天体（有时被称作Tyche（古希腊命运女神））隐藏在奥尔特云中。

Normal comets fall into the inner regions of the solar system from icy reservoirs in the distant Kuiper belt and Oort cloud.───通常来说，彗星来自距离遥远且冰天雪地的柯伊伯带和奥尔特星云然后掉入太阳系中的内层区域。

Kuiper Belt in addition to discrete disk ecliptic, the sun circle and still hypothetical Oort cloud.───在柯伊伯带之外还有黄道离散盘面、太阳圈和依然属于假设的奥尔特云。

They suggest that during its orbit it would regularly enter the Oort cloud, jostling the orbits of many comets there and causing some to fall toward Earth.

There it causes havoc in the Oort Cloud, a huge region surrounding the solar system that contains billions of bits of cosmic rubble left over from the formation of planets.

They start out in the Oort Cloud, a vast collection of perhaps trillions of small, icy chunks that hover at the very outer edges of the Solar System.

The objects that make up the Oort Cloud are too small and far away for WISE to see, but it will be able to track potentially dangerous comets and asteroids closer to home.

Every so often a comet gets flung out of the Oort Cloud, a swarm of comets on the fringes of the solar system[sentencedict.com], and gets close enough to Earth for us to see it.

The Oort cloud is a vast belt of dust and ice that is believed to lie around one light year from the Sun and is the origin of many of the comets that pass through our solar system.

This is still well within the Oort cloud, whose boundary is estimated to be beyond 50,000 AU.

The scientists have analysed the comets in the Oort cloud and deduced that 25 per-cent of them would need a nudge by a body of at least Jupiter size before they changed orbit.
