I came across this poem online. It's many of the poems about space that are posted over at the Adler Planetarium homepage (https://www.adlerplanetarium.org/blog/space-poetry/)
Galaxy by Anonymous
Nothing rhymes with galaxy, as every poet knows
Nothing rhymes with galaxy, it’s just how language goes
Nothing rhymes with galaxy, no matter what you’ve heard
Nothing rhymes with galaxy, so choose a different word
NOTHING rhymes with galaxy, although it’s all around
Nothing rhymes with galaxy, the poem you write will sound
Ridiculous at best, if you write in rhyming verse
So do not call it galaxy, or it will be the worst
