Two very interesting bodies have been found: Sedna, and VP113.

Sedna 和 VP113。

Sedna's orbit takes it an incredible 140 billion km from the Sun, while VP113 gets about half that far out.

Sedna 的公转轨道距离太阳1400亿公里，令人难以置信，而 VP113 距离太阳的距离只有这个距离的一半。

Even at its closest approach to the Sun, Sedna is further from Neptune than Neptune is from the Earth.

即使在最接近太阳的位置，塞德娜离海王星的距离也比海王星离地球的距离还远。

The bizarre part is that in those 10,000 years, Sedna never comes close to anything else in the solar system.

奇怪的是，在那 10, 000 年里，塞德娜从未接近过太阳系中的任何其他事物。

But Sedna never comes close to anything known in the solar system that could have given it that slingshot.

但是塞德娜从来没有接近太阳系中任何已知的可以给它弹弓的东西。

Remember that strange orbit of Sedna, how it was kind of pulled away from the Sun in one direction?

还记得赛德娜那条奇怪的轨道吗，它是如何从一个方向被拉离太阳的？

We named this object Sedna after the Inuit goddess of the sea, in honor of the cold, icy places where it spends all of its time.

我们以因纽特人的海洋女神命名这个物体塞德娜，以纪念它度过所有时间的寒冷、冰冷的地方。

We now know that Sedna, it's about a third the size of Pluto and it's a relatively typical member of those icy bodies out beyond Neptune.

我们现在知道塞德娜，它大约是冥王星的三分之一大小， 是海王星以外那些冰体中相对典型的成员。

If Sedna had had an orbit like this, that kisses the orbit of Neptune once around the Sun, that would have actually been really easy to explain.

如果赛德娜有这样的轨道，它与海王星绕太阳的轨道相吻合， 那实际上就很容易解释了。

When that cluster of stars dissipated into the galaxy, the orbit of Sedna would have been left as a fossil record of this earliest history of the Sun.

当那群恒星消散到银河系中时，塞德娜的轨道将作为太阳最早历史的化石记录而留下。

(Laughter) But my colleagues, Chad Trujillo and Scott Sheppard, did a better job, and they have now found several objects with orbits like Sedna, which is super exciting.

（笑声） 但是我的同事查德·特鲁希略和斯科特·谢泼德做得更好，他们现在已经发现了几个轨道像赛德娜一样的天体， 这非常令人兴奋。

I was so excited by this idea, by the idea that we could look at the fossil history of the birth of the Sun, that I spent the next decade looking for more objects with orbits like Sedna.

我对这个想法非常兴奋，对我们可以查看太阳诞生的化石历史的想法感到非常兴奋， 以至于我在接下来的十年里寻找更多具有像塞德娜这样的轨道的物体。
