I made a website that tells you, based on the year you graduated high school, what your school (probably) got wrong!

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.
Earth like? No. They're too small to hold any reasonable atmosphere. That doesn't rule out life, but it's unlikely. They're also likely too small to have subsurface oceans or things like that without being tied to a planet and having strong tidal forces squishing it, in which case it'd be a moon not a dwarf planet.
