Mercury

Eighty-Eight Days

The SunMercury
Mercury, on its way round the Sun. Drawn to be seen, not to scale: the order and the direction are real.

Mercury: the smallest planet, racing around the Sun in 88 days, swinging from 430°C to -180°C.

What the song is built on

  • The smallest planet, barely larger than Earth's Moon
  • A year lasts 88 Earth days; a single day lasts 176
  • Swings from about -180°C at night to 430°C in the sun
  • Scarred by the Caloris Basin, an impact 1,500 km across

Established astronomy. The music is an interpretation of it — see the curatorial policy.

SoundFast metallic electronic rock, driving 16th-note synth arpeggios, hammered anvil percussion, urgent male vocal, 140 BPM, cold and hot textures

Lyrics
[Intro] Run, little world, run [Verse 1] Smallest of the eight, barely bigger than a moon Iron heart and a rock-thin coat Eighty-eight days and the year is done While a single day takes one hundred seventy-six to go No air to hold the heat at night No cloud to keep the morning kind Four hundred thirty in the burning light Minus one eighty left behind [Chorus] Eighty-eight days, eighty-eight days Closest to the fire and I never slow Eighty-eight days, eighty-eight days The fastest thing the Sun will ever know [Verse 2] Caloris Basin, fifteen hundred wide A scar from when the sky threw stone Craters hold the ice inside their shade Water at the poles, and no one home Messenger came and circled me Then fell to rest upon my ground The swiftest one in the old stories Still running, never found [Bridge] Too close to look at, too quick to hold Too small to keep what the Sun gives out A world of iron, a world of cold Burning and freezing, turn about [Final Chorus] Eighty-eight days, eighty-eight days Closest to the fire and I never slow Eighty-eight days, eighty-eight days The fastest thing the Sun will ever know [Outro] Run, little world, run
