美科學家稱發現太陽系第九行星
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.
研究人員如今相當確定,太陽系中存在著第九顆行星.
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.
兩名來自加利福尼亞理工學院的科學家康斯坦丁·巴特金和邁克·布朗,稱新行星的質量大約是地球的十倍,其大氣中有含有氫和氦.據《科學》雜志報道,這顆神秘的X行星的運行軌道遠在海王星之外.
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.
《科學》稱,盡管研究人員目前尚未觀測到X行星的本尊,但他們在近距離觀測太陽時發現六個星體的排位很奇特,因此他們確信一定存在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.
科學家稱,這樣奇特的排位若是純屬巧合,其幾率僅為0.007%,因此他們堅信這一定是因為有第九顆行星存在的緣故.美聯社稱,科學家們相信五年內他們一定能用望遠鏡觀測到這個行星.
