这个系外行星的质量是地球的几倍，但是它足够小，能够由岩石构成，而不是像木星是一团巨大的气体。
The exoplanet is a few times the mass of Earth, but it should still be small enough to be rocky rather than a gas giant like Jupiter.
穿过小行星带继续前进，我们进入了气体巨行星区域：木星、土星、天王星、海王星，所有这些都使地球看起来像个侏儒。
Moving on through the asteroid belt we enter the realms of the gas giant planets: Jupiter, Saturn, Uranus, and Neptune, all of which dwarf the Earth.
“有充分的理由可以认定，同样的进程也会在其他行星，如木星和土星上发生”，德怀尔说。
"There's every reason to think the same processes are happening on other planets, such as Jupiter and Saturn," Dwyer said.

人们认为，液态的金属化氢可以存在于大质量行星，如木星、土星等的内部。
Liquid metallic hydrogen is thought to exist in the high-gravity interiors of Jupiter and Saturn.
由“超木星”的行星主要组成的体系可能要混乱得多。引力之间的叠加与抵消使所有行星的轨道形状变得十分奇特。
Systems dominated by very large "super-Jupiter" planets are probably far more chaotic, with gravitational tussles causing planets to end up in all sorts of strange orbits.
这300多颗日外恒星中大多数被发现的原因都是由于他们自身位置会受到巨型行星（大小与木星类似的行星）的公转影响而产生微小摆动。
The majority of the more than 300 "extrasolar planets" now known were spotted by watching the tiny wobble in stars' position as enormous, Jupiter-sized planets swung around them.
第一颗系外行星于1995年载入天文记录，到目前为止，天文学家们确认了515颗戏外行星的探测，其中大部分都是类似木星的巨行星。
The first exoplanet was catalogued in 1995 and astronomers have so far confirmed the detection of 515. Most are giant planets thought to resemble Jupiter.
如图所示，我们太阳系中的气态巨行星——木星、土星、天王星、海王星——大部分是由氢构成的。图片来自。

毫无疑问，太阳系所有的行星将围绕木星运转，因为在太阳系的行星中木星的质量最大。
There can be no doubt that they would all begin to revolve around Jupiter, because that planet has the largest mass.
自1992年以来，绝大多数已发现的行星都与其恒星较为接近，这更像是木星，因此，在这些行星上面很可能不会存在像地球上一样的智慧生命。
Most of the new planets that have been discovered since 1992 tend to be more like Jupiter and closer to their star, so it's highly unlikely that they support intelligent life like that found on Earth.
