An embarrassing problem that’s come up in recent years is a weird one: naming astronomical objects. It used to be easy! There were just a handful of planets, a couple of dozen moons, and some asteroids (comets are named after their discoverers, so no prob there).
But then astronomers decided to make better telescopes and more sensitive cameras, and the next thing you know there are thousands of objects that need names! Catalog designations are fine for a while, but we’re human, and humans like to name things.
