Perhaps we should just accept the fact there's obviously more than nine planets that orbit the sun regardless of size. It's only now we are realising this fact.
Maybe we should recategorize the trans-plutonian objects as "aspiring planets". You know, sort of like how black people like to call themselves "aspiring rappers". Even though most of them will never make it big in the industry?
The research in this video is incomplete. Alan Stern and other planetary scientists use the Geophyiscal definition (GPD) of a planet: "A planet is a sub-stellar mass body that has never undergone nuclear fusion and that has sufficient self-gravitation to assume a spheroidal shape adequately described by a triaxial ellipsoid regardless of its orbital parameters." This definition strictly speaks to an object's physical attributes and NOT its location. Look at the IAU definition of a planet: "A "planet" is a celestial body that: (a) is in orbit around the sun (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape (c) has cleared the neighbourhood around its orbit." Here are the problems: (a) "the sun" only applies to our solar system. Star would allow this definition to be apply to other star systems. (The IAU actually has separate definitions for Exo-planets, which means that somehow our planets and planets in other star systems have completely different definitions) (b) Good, but not as precise as the GPD. (c) Clearing the neighborhood is very vague. If you take the definition at face value, Earth is not a planet because our orbit encounters asteroids and other objects. Proponents imply that the mass of a planet has to outweigh the other bodies in or near its orbit, but if Earth's position were substituted with Pluto's, then Earth would cease to be a planet because the combined mass of the objects nearby in the Kuiper belt far outweigh it. The name Dwarf Planet has the very word "Planet" in it, so it should be a subcategory of planet rather than a thing that is not a planet. Our Sun is a Dwarf Star, but it is still a Star. In science we learn about new things all the time that change our understanding of our universe. Every scientific pursuit strives for accuracy of information and definitions. The 8 (and event 9) planet concept of our solar system is now outdated. Remember that the kuiper belt is part of our solar system. As such, at the very least the IAU should accept that we have many, many more planets in our solar system. The fact that the media and textbook writers use the IAU definition rather than the definition of what are used by planetary scientists (THE experts in this specific matter), adds more confusion to the situation.
Pluto is not a planet because it doesn't follow the 3rd rule to be one. "Having a Clear Path". So it's a Dwarf planet. 1. Spherical 2. Helio-Centric 3. *Clear Path* Simplified version// 1. Has to be a 3d circle 2. Has to spin around the sun 3. *Has to..Not have stuff in the way*

Maybe because there’s is 3709 comet ☄️ that are spiracle the orbit around the sun

Haha yes Pluto is a planet

💯💯💯
who else here from rick and morty lol
Plot twist. It's a moon that was never captured by a gas giant
kk
Pluto is not a planet because it doesn't follow the 3rd rule to be one. "Having a Clear Path". So it's a Dwarf planet.
1. Spherical
2. Helio-Centric
3. *Clear Path*
Simplified version//
1. Has to be a 3d circle
2. Has to spin around the sun
3. *Has to..Not have stuff in the way*
I still think it's a planet
Earth doesn’t qualify either. 🤡
