围绕太阳

It's the gravitational attraction between the sun and the planets that sustains the planets in elliptical orbits around the sun.

那是太阳和行星之间的万有引力。维持着众行星围绕在太阳周围的椭圆轨道上。

Now, four centuries later, we know that the Earth is a small planet circling a minor sun on the edge of just one of an estimated 125 billion galaxies.

而四个世纪之后的今天，我们已经知道了地球只是围绕着一颗并非显赫的太阳旋转的小小星球，我们的太阳处在银河系的一隅，而据科学家估算，这样的银河系大约有一千二百五十亿个。

It also appears to solve the deuterium problem but only if the rocky materials out near the earth's present orbit picked up some local water from the solar nebula ( the cloud of gas and dust surrounding the young sun ) before they accreted to form the earth.

同时，看上去它也解决了气含量的问题——但是只有当外来的岩石物质处于地球现今轨道附近时，并且在它们增生形成地球之前，从太阳的星云里(围绕着年轻太阳的气体和尘埃)获取了水时，这个问题才最终得到解决。

Nor is life likely to exist on the newly discovered planet because it is only 5 million miles from Pegasus 51, so close that it whizzes around the star once every four days and must be super hot Nevertheless, the fact that astronomers have found a planet around a sun like star bolsters their belief that others must abound in the universe.

生命也不大可能存在于新近发现的那颗行星上，因为它与飞马星座51的距离只有500万英里，如此之接近使它每4天围绕这颗恒星飞速旋转一次，那必定是超热的。尽管如此，天文学家已发现有一颗围绕类似太阳的恒星运行的行星，这一事实支持他们这样的信念：宇宙中其他的行星必然是很多的。

The earth , in revolving around thesun ,also t urns on it s own axis.

例 2 地球在围绕太阳运行的同时也绕轴自转。

Because the earth and other planets orbit around the Sun in the same plane, the planets appear to move through a belt in the sky called the "zodiac".

由于地球和其他行星围绕太阳的轨道在同一平面，行星带出庭动议通过天空叫&生肖&。

You'll probably need binoculars and a good sky chart to see faint Uranus, the 7th planet outward from the sun.

您可能需要望远镜和良好的天星图去观测那微弱的天王星，即围绕太阳外运行的第七行星。

Copernicus proved that Earth and the other planets in our solar system orbit our sun.

哥白尼证明地球和其他的太阳系行星是围绕太阳转的。

The zodiacal light is actually sunlight reflecting off dust particles that move in the same plane as Earth and the other planets orbiting our sun.

黄道光其实是处于地球同一星系中及其他围绕太阳旋转的行星的尘埃对太阳光的反射。

Because of this, scientists assumed that if you measure the speed of light in different directions, you should get different speeds since the earth is in orbit around the sun. In 1895 Albert Michelson and Edward Morley performed this experiment and surprisingly, saw no difference in the speed of light for different directions.

因此，科学家们认为，因为地球是在围绕太阳运行，如果我们沿不同方向测量光的速度，将得到不同的结果。1895年，阿尔伯特·迈克尔逊和爱德华·莫雷进行了这个实验，并且出乎意料地末能发现光在不同方向的传播速度有任何的差异。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
