Scientists said they have found evidence of a giant planet far out in our solar system.


科学家们说,他们发现了太阳系外有一颗巨大行星的证据。


In a statement,the California Institute of Technology–Caltech--said this planet travels a strange"highly elongated orbit in the distant solar system."


加州理工学院(Caltech)在一份声明中说,这颗行星运行的轨道“在遥远的太阳系中高度拉长”


The discovery was made by two researchers at Caltech:Konstantin Batygin and Mike Brown.They used mathematical modeling and computer simulations to find the planet.


这一发现是由加州理工学院的两位研究人员:康斯坦丁·巴蒂金和迈克·布朗共同完成的。他们用数学模型和计算机模拟来寻找这颗行星。


So far,there have not been any direct observations of the planet.


到目前为止,还没有对这颗行星的任何直接观测。

"My jaw hit the floor,"said astronomer Mike Brown,the moment he realized there might be a ninth planet.


“我的下巴撞到地上了,”天文学家迈克·布朗说,当他意识到可能有第九颗行星的时候。


The scientists said it would take this planet 10,000 to 20,000 years just to make one full orbit around the sun.The new planet,called"Planet Nine"has a mass about 10 times the size of Earth.


科学家们说,这颗行星仅仅绕太阳转一圈就需要1万到2万年的时间。这颗被称为“第九行星”的新行星的质量约为地球的10倍。


If they are right,the newly found planet would be the ninth planet in our solar system.Pluto had been called the ninth planet until 2006,when it was renamed a"dwarf planet."


如果他们是对的,新发现的行星将是我们太阳系的第九颗行星。冥王星一直被称为第九颗行星,直到2006年,它被重新命名为“矮行星”


Actual confirmation of a ninth planet would be very big news.


实际确认第九颗行星将是一个非常大的消息。


"This would be a real ninth planet,"Brown said in the statement."There have only been two true planets discovered since ancient times,and this would be a third.It's a pretty substantial chunk of our solar system that's still out there to be found,which is pretty exciting."


布朗在声明中说:“这将是一颗真正的第九颗行星。”自古以来,只有两颗真正的行星被发现,这将是第三颗。它是我们太阳系中相当大的一部分,至今仍有待发现,这非常令人兴奋。”


It is believed that the planet orbits,or travels,around the sun from a great distance.The planet Neptune's average distance to the sun is about 4.5 billion kilometers.But"Planet Nine,"could be 20 times farther away from the sun than that.


据信,这颗行星绕太阳公转或公转的距离很远。海王星与太阳的平均距离约为45亿公里。但是“九号行星”离太阳的距离可能是它的20倍。


While they did not get a picture of"Planet Nine"yet,the scientists say they are using the biggest—and best--telescopes on Earth to try to find"Planet Nine."


虽然他们还没有拍到“九号行星”的照片,但是科学家们说他们正在使用地球上最大最好的望远镜来寻找“九号行星”


They are also working on fine-tuning their computer simulations.They want to find out more about"Planet Nine's"orbit,and its impact on the outer part of our solar system.


他们还在对计算机模拟进行微调。他们想进一步了解“九号行星”的轨道,以及它对太阳系外部的影响。


Brown and Batygin reported their findings in the Astronomical Journal.They say that this new planet is so large that there should be no doubt that it is a true planet,once they confirm it.


布朗和巴蒂金在《天文杂志》上报道了他们的发现。他们说这颗新行星太大了,一旦他们确认了它,毫无疑问它是一颗真正的行星。


Robert Massey is with the Royal Astronomical Society in London.He told AFP that planets have been predicted before,and then were not found.


罗伯特·梅西在伦敦皇家天文学会工作。他告诉法新社说,行星以前就被预测过,后来就没有被发现。


But,he said the work of these researchers is definitely worth following up.


但是,他说这些研究人员的工作绝对值得跟进。


"It would be a really exciting thing to find.At the moment it's simply a prediction."


“这将是一件非常令人兴奋的事情。目前这只是一个预测。”
