美科学家称发现太阳系第九行星
Researchers are pretty sure they've found a new planet in our solar system
Researchers are now pretty certain there's a ninth planet in the solar system.
研究人员如今相当确定,太阳系中存在着第九颗行星.
Konstantin Batygin and Mike Brown, two CalTech scientists, say the new planet is about 10 times the mass of Earth and has an atmosphere of hydrogen and helium. Science magazine reports that the mysterious "Planet X" moves in a distant orbit beyond Neptune.
两名来自加利福尼亚理工学院的科学家康斯坦丁·巴特金和迈克·布朗,称新行星的质量大约是地球的十倍,其大气中有含有氢和氦.据《科学》杂志报道,这颗神秘的X行星的运行轨道远在海王星之外.
The researchers haven't observed Planet X itself, but believe it exists because of the unique configuration of six objects when they come closest to the sun, according to Science.
《科学》称,尽管研究人员目前尚未观测到X行星的本尊,但他们在近距离观测太阳时发现六个星体的排位很奇特,因此他们确信一定存在X行星.
The scientists say that there's a 0.007 percent probability that the configuration is due to chance, and instead are confident it's a ninth planet. They believe they will observe the planet with a telescope within five years, according to The Associated Press.
科学家称,这样奇特的排位若是纯属巧合,其几率仅为0.007%,因此他们坚信这一定是因为有第九颗行星存在的缘故.美联社称,科学家们相信五年内他们一定能用望远镜观测到这个行星.
