根據國際天文學聯會international astronomical union於2006年8月24日通過的行星定義，冥王星的行星資格被取消，並被界定為一類稱為矮行星的新天體。Pluto together with ceres an asteroid and eris a kuiper belt object are dwarf planets
冥王星連同穀神星小行星和厄里斯柯伊伯帶天體則歸類為矮行星。Pluto is not classified into either the terrestrial or jovian planets due to its special features
冥王星可算是九大行星中的蝙蝠，它不是類地行星，亦不屬于類木行星。Its density is roughly 2. 3 times that of water. usually, the jovian planets have density less than 2, while terrestrial planets have density more than 5
冥王星的密度約為水的2 . 3倍通常來說，類木行星的密度會小於2 ，而類地行星的密度則大於5 。The iau further resolves that pluto is a dwarf planet by the above definition and is recognized as the prototype of a new category of trans - neptunian objects
根據上述的定義，國際天文聯會進一步決定將冥王星撥歸為矮行星，並成為其中一類海王星外天體的原型。It is as important as the other eight planets in our understanding of the origin of the solar system because pluto and its family members carry some unique information that the eight planets cannot provide
冥王星對於我們研究太陽系的起源的貢獻，跟八大行星根本無分軒輊，冥王星及其他矮行星類的成員隱藏著獨特的解密鑰匙，這是八大行星不能提供和替代的。The key point is that pluto is totally different comparing to other eight planets. if pluto was discovered today, it would unlikely be classified as a major planet
只要知道冥王星大異于其他八顆行星便足夠了，可以斷言的是，假如冥王星是今天才被發現，它根本不可能被歸類為行星。分享友人
