1·A simulated low-speed crash between comparably sized planetoids yields a Pluto and a Charon, plus an icy debris disk that could coalesce into a Nix and a Hydra.
两颗相似大小的行星在模拟低速碰撞中产生了冥王星和卡戎，还有可以形成尼克斯和许德拉的并碎屑。
2·It becomes the fourth object known to be circling the distant world after the long-recognised Charon and recently observed Nix and Hydra satellites.
继公认良久的冥卫一(卡戎)及最近观察到的尼克斯卫星和许德拉卫星之后，它成为围绕这颗遥远星球运行的第四个实体。
3·Scene-specific commentary on all episodes with actors Jeffrey Donovan, Gabrielle Anwar, Bruce Campbell and Sharon Gless along with series creator Matt Nix.
和男演员杰弗里多诺万，加布里埃尔安瓦，布鲁斯坎贝尔和连同莎伦格里斯和剧集创建者马特尼克斯在所有全集场景细节评论。
4·If the probe finds that Nix and Hydra are mostly ice, it'll show Canup's simulation to be a smashing success.
如果探测器发现尼克斯和许德拉上多数都是冰，那么克纳普的模拟实验真是个巨大的成功了。
