Bro, this abstract doesn’t say anything close to what you said. 🤷‍♂️ I’m guessing you read only far enough to find what you thought confirms your misunderstanding, and thus you didn’t really read the paper. I know you didn’t read it, because there’s no way you could think this if you did. 🤷‍♂️ I mean, seriously. This was a peer reviewed publication in a top tier planetary science journal. Do you think it would really contain ridiculous claims like you think it does? Please try to engage in this discussion seriously.
Apparently you think that the cultural definition and the folk definition are two different things. They are exactly the same thing. Two different terms that mean exactly the same thing. It’s not just this way in astronomy. There are many folk taxonomies for biology and other topics, and they are always the cultural taxonomy, opposed to the scientific one. For example, in most folk taxonomies about animal, life, dolphins and whales were always classified as fish. So we cuttle fish, shellfish, and jellyfish. The scientific community had to fight the public to get them to give up those folk tax enemies and accept the scientific one, in which not everything living in the ocean is a “fish”.
The opposite to the cultural/folk taxonomy of planets is the scientific one — the one that came down from Galileo and has continued to evolve with the science, which is now called the geophysical definition. It came from the idea that planets are “other Earths” with geology and possibly life and civilizations.
The cultural/folk definition came from the idea that the cosmos is orderly and human-centric, as it was believed to be in geocentrism. When the public was finally forced to accept heliocentrism in the mid to late 1800s they did not accept the entire package; they smuggled in the orderly elements of geocentrism and astrology, creating the folk definition that is unhelpful for science. In that concept, only a few big primary planets reminiscent of geocentrism are called “planets”. They thought the asteroids are the result of a broken planet, because they did not believe an orderly cosmos would originally have asteroids. They also did not allow moons to be called planets, because in astrology the moons are in the same part of the sky as the primaries, so they serve no purpose in that orderly view of the cosmos, where the “planets” supposedly serve humanity. It was human-centric and completely unscientific.
That “cultural” or “folk” concept of planets is what the IAU unwittingly Incorporated into their 2006 definition. That happened because they weren’t familiar with the actual scientific development of the term “planet” both because they are not experts in that branch of science and because they did not take the time that was required to sort it out. They were in a big rush because they wanted to know if Mike Brown should be elevated into the pantheon of most famous astronomers with Le Verrier and Herschel. That was not a scientific concern. It was a purely cultural concern, and a pretty stupid thing to worry about if you ask me. A lot of astronomers did not feel that modern astronomers finding KBOs deserved to be put up to that level of veneration, so they thought it was urgent to quickly define “planet” in a way that kept these modern astronomers out of the pantheon of “planet discoverers who reshaped the Solar System”. So they thought about the cultural definition, made up an urban legend about why asteroids are no longer considered planets (completely disconnected from the real history but shaped to fit their preconceptions), then they broke the actual charter of the IAU to force an illegal vote in order to say that planets only include the ones that look like geocentric system except orbiting the sun. It was a total travesty!
The paper will walk you through that history with overwhelming evidence, because we exhaustively searched the entire literature on this topic, doing what the IAU should have done themselves.
