I'm curious about a couple of things:

If astronomers can demote Pluto, can't they rename Uranus?

Is Uranus only funny in English?

“If astronomers can demote Pluto, can’t they rename Uranus?”

They did in 2620 according to Futurama

Uranus (or alternate spelling "Ouranos") is the only planet named using the Greek name. All the other planets are named for the Roman pantheon.

If the naming convention were consistent, Uranus would be Caelus. But then the jokes wouldn't write themselves.
