The Post-Pluto Solar System: Should dwarf planets be common knowledge?

The loss of Pluto is the loss of innocence. Dedicated astronomers with amazing telescopes have destroyed our 9-planet, nursery rhyme, solar system and replaced it with an unknowable oblivion.

Our solar system currently consists of 1 star, 8 planets, 5 dwarf planets, 19 large moons, 165 small moons, 697 objects which could possibly be dwarf planets and a tremendous amount of small rocks and dust. Scientists find new objects every year and they are still working out definitions for things like “moon” and “dwarf planet”.

It will be some time, if ever, that a year will go by without new objects being found. How does a non-professional approach this new body of knowledge?

The mnemonic for remembering common knowledge objects changes all the time, one version is:
“My Very Educated Mother Cannot Just Serve Us Nine Pizzas—Hundreds May Eat!”

This pneumonic includes the 5 IAU recognized dwarf planets: Ceres, Pluto, Haumea, Makemake and Eris.

Part 1: Philosophy of teaching, specifically public K-12 education:
How do we approach this vast body of information?
What is the role of rote memorization?
How do we introduce information to people who didn’t ask for it?
What is the usefulness of common knowledge?
What do we tell students who ask, “When am I ever going to use this?”
How do we impart our excitement about the material to students?
How and when do we introduce scientific uncertainty?

Part 2: Learning about the solar system for ourselves.
How do solar winds affect the atmospheres?
Is Planet 9 really a mystery or is the paper just not yet ready to publish?
What elements and molecules are in the atmospheres and cores?
How do rings form?
What are the common properties of Trans Neptune objects?
What are some memorable characteristics of the 13 IAU recognized planets and dwarf planets?
