Ganymede

[Intro] Call me a moon if it makes it simpler [Verse 1] Five thousand two hundred kilometres across Wider than Mercury, and they call me small Because I turn around a bigger thing And that's the only rule at all A core of iron turning underneath A magnetic field that's mine alone The only moon that makes its own aurora Over an ice and rock-made zone [Chorus] Bigger than a planet, and still a moon Name me for what I orbit, not for what I am Bigger than a planet, and still a moon Ask the sky who's bigger, then ask again [Verse 2] Galileo found me in sixteen ten With Io, Europa, Callisto too Four lights that moved around another world And the old cosmology came unglued Salt water sleeps beneath my crust as well Deeper than Europa keeps hers Grooved terrain across my face Old ice remembering what it was [Bridge] Juice is coming, launched and climbing Europe's ship with my name in its plan Twenty-thirties, it will circle me The first moon but Earth's with a ship of its own [Final Chorus] Bigger than a planet, and still a moon Name me for what I orbit, not for what I am Bigger than a planet, and still a moon Ask the sky who's bigger, then ask again [Outro] Call me a moon I'll still be the biggest one there is
