第十颗行星可以扭曲外太阳系

A Tenth Planet Could Be Warping Our Outer Solar System

冥王星之外的柯伊伯带的天体渺小又遥远,但是它们能
The bodies of the Kuiper Belt out beyond Pluto are small and far away, but they have a lot
启发我们很多 即 它们的轨道意味深长 并且一项新的研究透露出可能存在一个
to tell us. Namely, their orbits speak volumes, and a new study is hinting that there might be a
大型天体潜伏在太阳系这片广阔的地区
gravitational mass lurking out in this distant region of our solar system.
并且 有人认为它有可能是第十个行星
And some people are saying it’s possibly a tenth planet.
但是 提出这种说法可能有点为时过早
But, that might be a bit premature.
总的来说 太阳系的行星运行轨迹相当统一
On the whole, our solar system is pretty neatly organized.
所有行星运行的轨道大体上是一致的
All the planets orbit more or less in line with each other.
它们的轨道大致都在“不变平面”上
They average out to be right along what’s called the “invariable plane”.
在距离太阳更远的地方情况更混乱
Things get chaotic even further from the Sun.
比如在5000-100000个天文单位外的奥尔特星云
Like in the Oort Cloud, which is 5,000-100,000 AU away.
奥尔特星云不是一个星盘
The Oort Cloud isn’t a disk.
它实际上是一团包围着我们的太阳系的星云
It’s actually a cloud that envelopes our solar system.
在距离太阳30-50个天文单位的柯伊伯带相对接近太阳
Relatively closer to the Sun in the Kuiper Belt, which is only about 30 to 55 AU from
天体环饶轨道运行十分有规律
the Sun, bodies orbit pretty regularly.
它们应该看起来像一块平坦的薄片
They should look sort of like a flat sheet,
因此 我们可以推测出第十星球的存在
which bring us to the alleged Planet Ten…
来自亚利桑那大学的研究者注意到超过600个更遥远的
Researchers from the University of Arizona noticed that over 600 of the more distant
柯伊伯带天体(KBOS)在“不变平面”上倾斜运行
Kuiper Belt Objects, or KBOs, have orbits inclined from the invariable plane by, on
平均 大约八度
average, about 8 degrees.
这只是细微偏离 但也足以指出 存在能扭曲这些轨道的
It’s a subtle deviation, but also significant enough to suggest that something big must
大质量天体
be warping those orbits.
它们离太阳很远 因此另一个大型天体的作用可能更加明显
They’re far enough from the Sun that another gravitational mass could be responsible.
比如你看这个旋转的陀螺 它是太阳系的模型
If you look at a spinning top… it sort of models things in the solar system.
想象“不变平面”穿过其中部
Imagine the invariable plane cutting through the middle.
太阳系的内部是稳定的 就像这个陀螺
The inner solar system is steady, like the top.
如果这个陀螺摇晃 是某种作用力导致的
If the top wobbles, something is causing it to do so.
他们看到那600多个天体全被施加轻微压力 胡乱摆动得像
The over 600 objects they looked at are wobbling pell-mell like a handful of spinning tops
一把旋转的陀螺 并且他们通过证据认为这个现象并不是侥幸或数据错误
all nudged differently, and the observational evidence says it’s not a fluke or bad data.
某种未知天体引起了它们轨道平面的变化
Something has affected them.
根据研究者的计算 这些不规则的轨道可能是由
According to the researchers’ calculations, the irregular orbits could be explained by
一个距太阳60个天文单位的 质量和火星相近的大型天体导致的
a gravitational mass around the size of Mars orbiting about 60 AU from the Sun.
它肯定不是行星九 顺道说明 与行星九相比 那个大型天体与柯伊伯天体的距离更大
It’s definitely not the theorized Planet Nine, by the way, that’s way larger and
大约十倍远
about ten times farther away.
我们制作了一个关于它的视频
We did a video about it.
但是就像行星九 行星十也是一个理论上的天体 可能存在 可能不存在
But like Planet Nine, Planet Ten is still a theoretical body that may or may not exist,
并且我们还没有见过它 因为我们没有在正确的地方观察
and we might not have seen it yet because we haven’t looked in the right place.
或者它根本不存在――这是有可能的:最近的一段历史上有一颗星星在我们的太阳系上快速飞过
Or it might not exist at all — it’s possible: a star whizzed by our solar system in recent
(从天文学的角度来说)这颗星星撞开周边的轨道 随心所欲地在自己的
history (astronomically speaking) and kicked those orbits around, then went on its merry
轨道上运行
way.
关于所有在宇宙中的大的 被预言的事物 天文学家将需要做一些继续的
As with all big, predicted things in space, astronomers will need to do some follow-up
观察来进一步证实行星十的存在与否
observations to confirm Planet Ten’s existence… or non-existence.
