I appreciate your contribution to the discussion. I’d have to point out that Pluto both is and is not a planet, depending on the context — it depends on whom you ask and the situation in which you ask.
What would you say to scientists and laypersons who consider Pluto to be a planet? How would you persuade them to your own viewpoint? Please give at least three examples and use at least three paragraphs.
Pluto is a dwarf planet. It feels like less of a "is and is not" situation, and more of an "isn't, but was once thought to be" situation.
Some people remember being told that it was a planet when they were kids and they cling to that even though we've learned that it doesn't make sense to call it a planet anymore.
Apart from that it shows up as a planet in literature, almost all of which was written before we knew better, just like how the idea of earth being at the center of the universe shows up in literature and was once a part of our culture. The geocentric model had passionate holdouts too, but we've mostly moved on from that idea since and I think we're better off for it.
For scientists and laypersons who aren't just holding onto "planet" for sentimental reasons, I'd recommend the book "How I Killed Pluto and Why It Had It Coming"
A geocentric model is observably incorrect.
The word “planet” is neither true nor false. Different people use it to refer to different things.
Kind of like the word “tree.” Some things are trees and some things are not — and it really depends on whom you ask and when you ask them. Most people are able to get along and allow people to refer to whatever trees they want to, because it’s a free country and it really doesn’t make sense to try to control other people over something like that.
