查询词典 asteroid

During the simulation of the 2029 encounter with Apophis, it became clear that under the right conditions, the asteroid would be deflected into a new orbit that would send it back to threaten Earth exactly seven years later.

在模拟2029年遭遇阿波菲斯时可以清楚地看到，处在正常状态下的小行星将偏离到一个新的轨道上，而这条轨道将使阿波菲斯在7年之后再次威胁地球。

Now two studies published in the journal Nature suggest that notion may be all wet. Because at least one asteroid appears to be coated by a thin layer of ice. And just that kind of asteroidal frosting could have been the source of our water here on Earth.

现在，《自然》杂志发表的两项研究告诉我们这一观念恐怕是大错特错的，因为我们至少已发现了一颗小行星表面覆盖着一层薄冰，而且只有这种小行星结霜有可能是地球上水的来源。

Among the other worlds orbiting Bespin's star are Miser, Orin and the Velser's Ring asteroid belt.

其他围绕贝斯平的恒星旋转的星球是米瑟、奥林和维尔瑟的环状小行星带。

Formed by the impact of a large asteroid or comet, Caloris is one of the largest, and perhaps one of the youngest, basins in the Solar System.

卡勒瑞斯是由于一个大型的小行星或者是彗星的影响而构成的，是太阳系中最大，也可能是最年轻的盆地之一。

If you insist on worrying about the global economy, better to get riled up about a Chinese economy showing signs of overheating, North Korea's missile-happy regime, or a killer asteroid careering toward the planet unbeknownst to us all.

如果说仍难以消除对全球经济的担忧，就应将更多注意力转向中国经济发展中出现的经济过热迹象、朝鲜的导弹威胁以及其他无法预知因素。

According to this scenario, researchers could never find evidence of such early chondrules because all these objects would have been destroyed by the melting of the chondritic asteroid s into which they accreted.

在这个情形下，研究人员恐怕永远也无法找到如此早期的球粒证据，因为所有这些物体在聚合的过程中，都会因为球粒陨石小行星熔化而被破坏。

As the Earth-bound scientists toil, Rosetta itself will continue to zoom across our Solar System, next swooping again by the Earth in 2009 November, flying by asteroid 21 Lutetia in 2010 July, and finally landing on comet Churyumov-Gerasimenko in 2014 November.

当科学家在忙碌的同时，罗塞塔号也将继续在太阳系中飞驰，预定于2009年11月越过地球、2010年7月飞越小行星21Lutetia ，并于2014年11月最终降落在 Churyumov-Gerasimenko 彗星之上。

Abundance of salt-alkaline megatherm Classopollis-Ephedripites assemblage in a limited time illustrates a short duration of dry hot climate by latest Cretaceous. Such extreme climatic change and ecologic overturn are possible causes of the dinosaur extinction in the study area. Other factors, such as asteroid impact and large volcanic eruption triggering global mass extinction caused the regional climate change.

嘉荫群上部渔亮子组中膏岩层和耐高温、抗盐碱的克拉梭粉-麻黄粉组合在短时间内的大量出现，说明晚白垩世末期出现有短暂的干热气候，这种气候的突然转变以及伴随的生态系统的紊乱可能是嘉荫地区恐龙大量死亡的重要原因，但不排除诸如天外星体碰撞地球、大规模火山喷发等引发白垩纪末恐龙全球灭绝的因素，后者更可能是引起气候变化的直接因素。

As to what happened to the Palaeocene fauna, the evidence points not towards an errant asteroid but to a giant burp from the oceans, which released a huge amount of methane.

至于古新世时代末期动物群到底发生了什么致使它们灭绝，有证据指出这是海洋的一个惊涛骇浪所散发出的大量甲烷气体所致使的，而并没有提到所谓的偏轨行星。
