The Heart That Stayed

PlutoCharon
Pluto and Charon. Drawn to be seen, not to scale: the order and the direction are real.

Pluto: planet from 1930 to 2006, with a heart of nitrogen ice and a year that lasts 248 of ours.

What the song is built on

  • A planet from 1930 to 2006, then a dwarf planet
  • A heart-shaped plain of nitrogen ice sits on its face
  • One of its years lasts 248 of ours
  • New Horizons passed it in 2015 and showed us mountains of water ice

Lyrics
[Intro] You can take the word back You can't take the heart [Verse 1] Clyde Tombaugh found me in nineteen thirty A boy from a Kansas farm with a homemade glass They let a schoolgirl give me a name And for seventy-six years, the ninth I was Then two thousand six, a vote, a word A definition I did not fit Dwarf planet, they said, and the textbooks changed And children cried about it [Chorus] But the heart is still here Eight hundred miles of nitrogen ice Shaped like something you would draw On a world you were told to stop loving twice [Verse 2] Two hundred forty-eight of your years To go once around the Sun I cross inside of Neptune sometimes Then out again, and on New Horizons came in twenty fifteen Nine years flying to a single day Mountains of water ice three thousand metres tall And Charon turning with me all the way [Bridge] Tombaugh rides on that spacecraft still An ounce of ash, a promise kept The man who found me got to pass me While the rest of the world slept [Final Chorus] And the heart is still here Eight hundred miles of nitrogen ice Shaped like something you would draw On a world you were told to stop loving twice [Outro] Call me what you like I'm still out here, turning
