Decided to make a handy graphic after seeing a lot of misinformation spread around tumblr. Current science isn’t perfect and definitions are bound to change, but I wanted to push back against the hostile attitude against it because it seems like a lot of people are being hostile for the wrong reasons.
Please let me know if there are any factual errors, thank you :)
blah blah blah. I know all this. The IAU’s third criteria was and is wrong. All the dwarf planets should be considered planets. Yes that means we have 13 confirmed, and possible 100s unknown past Pluto. So what, that is just how it is. The IAU currently tries to claim a “dwarf planet” is not a subgroup of “planet”. This is absurd on the face of it. They should use a different name if that is what they want to do (they’d still be wrong, but only in one place instead of two).
On the other hand, if you want to make “dwarf planet” a subgroup of “planet” and make the “cleared orbit” rule the distinguishing feature, that might be workable.
