But Jupiter's moon Ganymede is bigger than Mercury.

但木星卫星木卫其实比水星还大。

To date,   we have not proved that life arose on Mars or Ganymede, for all the conjecture on that front.

迄今为止， 我们还没有证明生命起源于火星或木卫，尽管这方面有很多猜想。

The first is Titan, a monster satellite that's actually bigger than Mercury, not that much smaller than Mars, and second in moon size ranking only to Jupiter's moon Ganymede.

土卫六（泰坦），颗比水星大、比火星小不了多少巨型卫星，它仅次于木卫之外最大卫星。

Her chair being a far more comfortable one than his she still slept on inside his great-coat, looking warm as a new bun and boyish as a Ganymede.

她椅子比舒服得多， 她仍然睡在大衣里面， 看起来像新面包样温暖， 像木卫样孩子气。

After a few years of whizzing around Jupiter and its moons, in 2034 JUICE will enter orbit around Ganymede — which, being bigger than the planet Mercury, is actually the solar system's largest moon.

在围绕木星及其卫星呼啸穿梭数年之后，2034 年 JUICE 将进入围绕木卫道，而它比水星还大，太阳系最大卫星。

Whether Ganymede' s oceans have a similar chemical endowment is one of the biggest questions about the moon, says Leigh Fletcher, a planetary scientist at the University of Leicester, and one of the scientists working on the mission.

莱斯特大学行星科学家利弗莱彻此次任务科学家之，说，木卫海洋否有类似化学物质有关这颗卫星最大问题之。

Ganymede is the largest moon in our solar system.

伽尼墨德(木卫)太阳系里最大卫星。

Ganymede is one of Jupiter's likely ocean-bearing moons.

木卫可能含有海洋木星卫星之。

They're called Ganymede, Callisto, and Europa.

这几分别叫木卫、木卫四和木卫二。

They're mostly rock and ice, though Ganymede, the biggest, may have an iron core.

它们大多岩石和冰构成，最大木卫可能有铁核。

Ganymede is also criss-crossed with large grooves.

木卫上也布满了纵横交错沟壑。

The biggest of Jupiter's moons is Ganymede.

木星最大卫星木卫（盖尼米德）。

Ganymede is the largest moon in the solar system, and is even larger than the planet Mercury!

木卫太阳系中最大卫星，体积甚至超过水星！

The probe' s cameras will add much more detail to the existing, low-resolution maps of Ganymede' s surface.

探测器摄像头将为现有低分辨率木卫表面地图添加更多细节。

Io, Europa, and Ganymede are close enough to interact gravitationally, providing a source of heat for their interiors.

木卫、木卫二和木卫引力相互影响，这它们内部热量来源。

Oh, one more thing: both Ganymede and Io are magnetically connected to Jupiter.

木卫和木卫都通过磁场与木星联结。

Size isn't the only planet-like characteristic of Ganymede, either.

大小也不木卫唯类行星特征。

Ganymede, on the other hand, is further out in a safer, less radiation-riddled part of Jupiter's neighborhood.

另方面，木卫离木星更远，在更安全、辐射更少地方。

The four largest moons, Io, Europa, Ganymede, and Callisto, are large enough to be seen from Earth with a telescope.

从地球上就可以用望远镜看到最大四颗卫星，木卫，木卫二，木卫，木卫四。
