Moonshine

Now Io belches sulfur in its sleep,
Iapetus the two-faced has a ridge;
While Titan hides its Kraken in the deep,
Europa may have microbes in the fridge.
Old Ganymede’s the largest of the brood,
And Luna’s most familiar of them all;
Dark Umbriel’s bright crown improves its mood –
Dione’s just a boring icy ball.
Callisto’s cratered by a billion years,
Phobos is a potato on the run,
While Deimos at its brother gently peers;
Enceladus’s oceans could be fun.
And Charon is our New Horizons’ hope –
And Triton is a backwards cantaloupe.
