NASA chief argues Pluto should still be considered a planet

美國(guó)宇航局局長(zhǎng)認(rèn)為冥王星仍應(yīng)被視為一顆行星

Poor Pluto was declassified from being a planet in our solar system to just a humble dwarf planet 13 year ago.

可憐的冥王星在13年前被解密，從太陽(yáng)系中的一顆行星變成了一顆不起眼的矮行星。

Despite it being over a decade since this decision was made, the topic is still hotly disputed and there are those who think Pluto should be labeled as a planet once more.

盡管做出這一決定已經(jīng)有十多年了，但這個(gè)話(huà)題仍然存在激烈的爭(zhēng)議，有些人認(rèn)為冥王星應(yīng)該再次被貼上行星的標(biāo)簽。

The International Astronomical Union made the final decision but it seems NASA administrator Jim Bridenstine has put himself firmly in Pluto’s corner.

國(guó)際天文學(xué)聯(lián)合會(huì)做出了最后的決定，但看起來(lái)美國(guó)宇航局局長(zhǎng)吉姆·布里登斯廷已經(jīng)堅(jiān)定地站在了冥王星的立場(chǎng)上。

Bridenstine recently spoke out about his support for Pluto as a planet during a tour of the Aerospace Engineering Sciences Building at the University of Colorado Boulder.

布里登斯汀最近在參觀(guān)科羅拉多大學(xué)博爾德分校(University of Colorado Boulder)的航天工程科學(xué)大樓時(shí)，公開(kāi)表示支持冥王星是一顆行星。

The NASA chief said: “Just so you know, in my view, Pluto is a planet.”

美國(guó)航天局局長(zhǎng)說(shuō)：“你知道，在我看來(lái)，冥王星是一顆行星。”

“You can write that the NASA administrator declared Pluto a planet once again. I’m sticking by that, it’s the way I learned it and I’m committed to it.”

“你可以這樣寫(xiě)，美國(guó)宇航局局長(zhǎng)再次宣布冥王星為行星。我堅(jiān)持這一點(diǎn)，這是我學(xué)習(xí)的方式，我致力于這一點(diǎn)。”

Bridenstine’s lighthearted comment doesn’t change Pluto’s classification but it does bring to light the ongoing debate once more.

布里登斯廷輕松的評(píng)論并沒(méi)有改變冥王星的分類(lèi)，但它再一次揭示了正在進(jìn)行的爭(zhēng)論。

Pluto was removed from the list of nine planets in August 2006 mostly because its properties were more suited to the definition of a dwarf planet.

冥王星在2006年8月被從九大行星名單中刪除，主要是因?yàn)樗男再|(zhì)更適合于矮行星的定義。

The difference between a dwarf planet and a planet is largely to do with the space around it.

矮行星和行星的區(qū)別很大程度上與周?chē)目臻g有關(guān)。

Planets have a clear area around their orbit whereas dwarf planets do not.

行星在其軌道周?chē)幸粋€(gè)清晰的區(qū)域，而矮行星則沒(méi)有。

There are also many other celestial objects a similar size to Pluto with unclear orbits so some scientists have argued that if Pluto where to be considered a planet then all those other objects would have to be too.

還有許多其他的天體與冥王星大小相似，軌道不明，因此一些科學(xué)家認(rèn)為，如果冥王星被認(rèn)為是一個(gè)行星，那么所有其他天體也必須是。

However, Pluto has other features like a multilayered atmosphere, moons, weather and organic compounds that all make the issue regarding its planet status even trickier.

然而，冥王星還有其他的特征，如多層大氣、衛(wèi)星、天氣和有機(jī)化合物，這些都使得它的行星地位問(wèn)題更加棘手。
