美国有线新闻 CNN 木星直径约是地球直径的11倍（在线收听）

In terms of its diameter, which of these planets is about 11 times the size of Earth?

就其直径而言，以下哪个行星的直径大约是地球直径的11倍?

Venus, Saturn, Jupiter or none of these?

金星，土星，木星还是都不是?

The largest planet in our solar system, whose diameter is about 11 times the size of Earth’s is Jupiter.

我们太阳系中最大的行星，其直径大约是地球的11倍。

AZUZ: Compared to earth’s mass, Jupiter is thought to be much larger than that. And scientists say NASA’s Juno spacecraft has led to new findings about Jupiter.

木星的质量要大于地球的质量。科学家表示，美国宇航局的“朱诺”号宇宙飞船对木星有了新的发现。

For one thing, they believe the planet’s surface has bands of gas and winds that flow very quickly in opposite directions. They don’t know how deeply these bands extend, though, but information from Juno has led them to conclude that Jupiter’s outer layer extends 1,900 miles beneath the surface of the planet.

一方面，他们认为地球表面有大量的气体和气流，它们以相反的方向快速流动。他们不知道这些气流带的深度，但是来自朱诺的信息让他们得出结论，木星外层延伸到地球表面下1900英里。

So, how did they come up with this? Juno took measurements of Jupiter’s gravitational field, which scientists use to more deeply analyze the planet. They also concluded that though Jupiter’s interior is thought to be fluid, it rotates like a solid body.

那么，他们是怎么得出这个结论的呢?朱诺测量了木星的引力场，科学家们用它来更深入地分析这个星球。他们还得出结论，尽管木星内部被认为是流体，但它像固体一样旋转。

The Juno mission cost the U.S. a little over $1.1 billion. It’s hoped to help scientist better understand the solar system’s largest planet.

朱诺号的任务花费了美国11亿多美元。希望能帮助科学家更好地了解太阳系最大的行星。

Jupiter is located fifth in line from the sun. Both Jupiter and the Juno’s spacecraft were named after characters in Roman mythology.

木星位于距离太阳1/5的位置。木星和朱诺号宇宙飞船都是以罗马神话中的人物命名的。
