| 2. | First of all , let us look at the approved iau definition of a planet in our solar system 首先,让我们重温国际天文联会通过有关太阳系行星的新定义。 |
| 3. | After the resolution of international astronomical union in august 2006 , pluto is demoted to a dwarf planet 2006年8月,国际天文联会表决通过行星的新定义。 |
| 4. | Now , a group of astronomers are petitioned against the new definition , so the story is not yet end 现在,一群天文学家正向国际天文联会请愿并要求重新定义行星,冥王星的故事和最终命运可说是仍未完结。 |
| 5. | Another major problem is that the iau working group is not open enough and there is no formal consultation before the assembly 另外,国际天文联会工作小组的工作方式也不够透明公开,在大会前并没有作任何正式的谘询。 |
| 6. | 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 根据上述的定义,国际天文联会进一步决定将冥王星拨归为矮行星,并成为其中一类海王星外天体的原型。 |
| 7. | Before 1930 , constellations were regions in the sky with only fuzzy boundaries . in that year , the international astronomical union put the scheme of constellations on a definite system 在1930年以前,星座只是天上一个一个笼统的区域,这一年,国际天文联会正式把全天划分为 |
| 8. | The new object , dubbed " quaoar " by the two astronomers after a creation god of the tongva native american tribe , was provisionally designated as " 2002 lm 60 " by the international astronomical union 夸欧尔一词,源自美国原始部族神话,代表创造之神。而国际天文联会更给这颗天体的临时编号为" 2002lm60 " 。 |
| 9. | I feel that it is unfair and i would see that the new iau definition is to reclassify pluto . although pluto is not a planet , it is the prototype of a new category and it is a very significant object 我觉得这是不公平的,国际天文联会的新定义是要将冥王星从新分类,虽然冥王星不再是行星,但它是矮行星类天体的原型,在科学上自有其重要性。 |
| 10. | Since pluto discovered in 1930 , the term " nine planets " have been used for many years , but soon , the term " nine planets " will become history , as the international astronomical union will formally define what is " planet " 自1930年冥王星被发现,九大行星这名词一直沿用至今,但很快,九大行星这个名称将会成为历史,因为国际天文联会将会重新定义何谓行星。 |
