Earth's moon, Saturn's Titan, Jupiter's Callisto, or Jupiter's Ganymede?

地球星，土星土六，星四，还星Ganymede?

Ganymede is the largest moon in our solar system.

伽尼墨德(三)太阳系里最大星。

Ganymede is also criss-crossed with large grooves.

三上也布满了纵横交壑。

They're called Ganymede, Callisto, and Europa.

这几个分别叫三、四和二。

The biggest of Jupiter's moons is Ganymede.

星最大星三（尼米德）。

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

三可能含有海洋星星之一。

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

大小也不三唯一类行星特征。

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

三和一都通过磁场与星联结。

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

三太阳系中最大星，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三表面地图添加更多细节。

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

另一方面，三离星更远，在更安全、辐射更少地方。

Ganymede has a surprise well below its surface, too: Oceans of water!

液态水海洋！

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星，一，二，三，四。

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，最大三可能有一个铁核。

There was Ganymede, the beautiful boy who Zeus made drink-bearer to the gods.

有伽倪墨得斯，一个美丽男孩，宙斯让他成为众神侍酒者。

And unlike the abyss that may exist inside Ganymede, for instance, inaccessible, deep inside Europa is somewhat closer to the surface.

例如，与三内部可能存在深渊不同，二深处无法进入深渊更浅。

Jupiter's moons include the largest in the solar system, Ganymede, an ocean moon called Europa and a volcanic moon named lo.

星星包括太阳系中最大三，一颗名为二海洋星和一颗名为lo火山星。

Juice will investigate three of the so-called Galilean moons-Callisto, Europa and Ganymede, all of which are thought to have subsurface oceans.

“果汁”探测器将调查三颗所谓伽利略星——四、二和三，这三颗星都被认为拥有地下海洋。

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

一、二和三引力相互影响，这它们内部热量来源。

Like Ganymede and Io, the interior of Europa is kept warm by tidal flexing from the other moons, keeping the ice melted.

和三、一一样，二内部也因为其他星潮汐作用而被加热，从而使冰保持融化状态。
