Reply to comment by 10secondmessage in TIL Pluto hasn't completed an orbit around the sun since its discovery. Pluto's orbit takes about 248 years, and Pluto was discovered in 1930. by irbinator

Planets up to Saturn were known to the ancient Greeks, but Uranus, Neptune and Pluto were named after the invention of the telescope (with the first one in 1781), and they just continued the naming convention in the same way. All the moons, dwarf planets, planetoids and other things in our solar system were named for Roman myths as well, but most of them weren't known until much more recently

Many of the more recently discovered dwarf planets are named after deities from other cultures. Haumea is Hawaiian, Makemake is Rapa Nui, Sedna is Inuit, Gonggong is Chinese. The moons of Uranus are named after English literary characters from Shakespeare and Alexander Pope.

Thanks for adding this, I did know, but since it had nothing to do with the point I was making I failed to mention it
