Neptune

海王星

Neptune is the solar system's eighth and outmost planet. It has the fourth largest diamester of the planets, and its mass is the third largest. In fact, it is 17 times the mass of Earth, Although Uranus is the near twin of Neptune, Neptune is slightly more massive. Neptune is named after the Roman god of the sea.

海王星是太阳系第八颗也是最远的一课行星。它在太阳系行星中,直径位居第四位,质量位居第三位,是地球的17倍。尽管天王星与其像是双子星,但是海王星的质量更大。海王星是根据罗马海神的名字来命名的。

Nepthane's atomosphere is mostly made up of hydrogen and helium. There are also traces which has similar amounts of mathane. These cause the planet's blue appearance. It is more vivd than that of Uranus, which has similar amounts of methane. Therefore, it is assumed that an unknown component causes Neptune's intense color.

海王星的大气层是由氢和氦组成的。大气中含有微量的甲烷气体,这海王星看上去是碧蓝的。但是海王星却比含有相同含量甲烷的天王星更加蔚蓝,所以就有人认为,这是海王星大气中含有某些不为人知的成分才造成了这一现象。

This planet has many strange aspects that make it interesting to scientists. One such aspect is that Neptune has the strongest winds of any planet in the solar system. They blow as fast as 2,500km per hour. Also, there are thirteen confirmed moons orbiting Nepture. Notable for its retrograde orbit is Triton. This moon has a nirtogen/methane atomosphere and is very cold.

海王星许多不可思议的奇怪现象让很多科学家都对其很感兴趣,其中一点就是海王星上有比任何太阳系行星都强劲的大风,风速可以达到每小时2,500公里。另外,已有13颗已被证实的卫星围绕海王星,其中最著名的要数因逆行驶的特利顿卫星。这颗卫星的大气由氮和甲烷组成,且温度很低。

 The temperature at the top of Neptuen's  clouds stays around -210 degrees Celsius. This makes it one of the coldest planets in the solar system. This coldness is cuased by Neptune's great distance from the sun. The temperature at the center of the planet is about 7,000 degrees Celsius due to extremely hot gases and rock in the center. This is hotter than the surface of the sun. But the planet's outermost layers are extremely cold.

海王星大气层的顶部温度保持在零下210摄氏度左右,这使得海王星成为了太阳系行星中最冷的行星。低温的由于其离太阳的超远距离造成的。海王星中心极其炎热的气体和岩石使得内部的气温达到了7,000摄氏度 ,这个温度比太阳表面的温度还要高。但是海王星的最外层确实极其的寒冷.                                        

The Voyager 2 probe flew by Neptune in 1989 and discovered a region called the Great Dark Spot. This spot was viewed on its southern hemisphere. This is comparable to the Great Red Spot on Jupiter. Also, faint rings have been detected around the planet. These are much similar than Saturn's rings. These rings were discovered by Edward Guinan's research team. They were at first thought to be incomplete, fading out before they rounded the planet, But Voyager 2 disproved this belief with photos of complete rings。

旅行者2号在1989年飞到海王星,在其南半球发现了和木星上类似的大红斑。另外,在行星的周围也检测到了一些微弱的环,这些环比土星的环要小很多,这些由爱德华·吉男小组发现的环起初被认为是不完整的,因为它们在围绕行星之前就逐渐消失,但是随着旅行者2号发回的完整环的照片之后,这一说法便被否定了。
