No, because they are stars. Stars are not planets.
Plus it totally defeats the "My Very Energetic Mother Just Served Us Nine Pizzas" mnemonic. Without Pluto, she just served us nine....nine what?!
Charon and Eris are stars now?
I don't think so.
Charon is one of Pluto's moons, and Eris is a dwarf planet like Pluto
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and the dwarf planets Pluto, Haumea, Makemake, and Eris
I think they should just add the dwarf planets to the list and be done with it. We already have 2 classifications of planets in the solar system, why not 3?
Oops, didn't see your other post.
Ok, just make the pizza Ham, Mushroom and .....um......Eggplant?
