So where did this possible planet come from? Scientists have previously speculated that there could be a missing planet in our solar system, with some theorizing that a collision caused it to be ejected out of our system some 4 billion years ago. That collision may have been with Jupiter.
那么这颗可能存在的行星到底来自哪里呢？科学家们曾根据理论研究猜测,大约四十亿年前的一场碰撞将一颗行星弹出太阳系,从此这颗行星便下落不明.碰撞的另一颗行星可能是木星.
"Although we were initially quite skeptical that this planet could exist, as we continued to investigate its orbit and what it would mean for the outer solar system, we become increasingly convinced that it is out there," Batygin said in a statement. "There is solid evidence that the solar system's planetary census is incomplete."
"虽然一开始我们对这颗行星的存在持怀疑态度,但是随着我们进一步研究其运行轨道以及其对外太阳系的影响,我们越来越确信它的存在."巴特金在一份陈述中如是说道,"有确切证据表明,行星普查的数据并不完整."
Batygin and Brown described their findings in The Astronomical Journal on Wednesday.
20日,巴特金和布朗在《天文学期刊》中阐述了他们的发现.
The discovery is also the second time that Brown has reshaped the way we think about the solar system. In 2005, he made a key discovery that led scientists to reclassify Pluto as a dwarf planet. In a statement on Wednesday, Brown -- whose Twitter handle is @plutokiller -- alluded to the role he played in getting Pluto declassified, noting that the new discovery was 5,000 times the mass of Pluto and was definitely a planet.
这个新发现也是布朗第二次改变我们对太阳系的看法.2005年,他的一项重要发现引导科学家们将冥王星重新归类为矮行星.布朗的推特名是冥王星杀手（@plutokiller）,暗示自己在推翻冥王星地位这一事件中起主要作用；他于20日发表的一份陈述中说道,这次的新发现,其质量是冥王星的5000倍,因此它绝对是一颗行星.
"All those people who are mad that Pluto is no longer a planet can be thrilled to know that there is a real planet out there still to be found," he said.
布朗说："冥王星的行星地位被推翻后,许多人很生气,不过现在有一颗真正的新行星正等待着去发现,这可有他们乐呵的啦."
