Neptune does not clear Pluto's orbit.
So, everybody decided to ditch Pluto twelve years ago, and while everyone had reasons, I just discovered the alleged real reason the other day--Pluto does not clear its own orbit.
Am I going to explain that? No. This scientist says that the definition that disqualified Pluto as a planet does not make sense and does not have a foundation: https://phys.org/news/2018-09-pluto-...ed-planet.html I do not know if that guy mentioned it, but if Pluto does not clear its own orbit, neither does Neptune. Neil Degrassy Tyson says that if we classify every spherical body in the solar system as a planet we would have fifty. Nobody calls Endor a planet, even though it had adequate gravity and supported life. I bet you do not even know the name of the host planet! Actually, the planet is Endor. Oh well. 1. Adequate mass to become spherical. 2. Not orbiting a larger planet. 3. ???? 4. Planet! |
The Force is strong with this one.
I guess some planets are more planet than others. Pluto is a dog and Goofy is a dog, but somehow Pluto is more dog than Goofy. (Actually Goofy is based on a dingo: Canis lupus dingo, while Pluto is a mixed breed dog: Canis lupus familiaris.) Most people produce more endorphins when accompanied by dogs. |
Is that when walking the dog or being chased by it? :)
|
Goofy occupies a different ecological niche to Pluto.
Pluto is a monkey analogue. Goofy is a human analogue. - Fudge it, I agree with him. Sphericity. Because the "Dwarf Planet" classification doesn't make much sense when some of those dwarves don't have enough mass to form into a perfect sphere. Also, why does Mercury get a free pass when it is smaller than some moons? |

Several moons are larger than the planet Pluto and two moons are larger than the planet Mercury. There also are many small moons that may be asteroids captured by their planets.
The smallest moons are seven miles in diameter, except asteroids have moons, too. In 1993, an tiny moon called Dactyl was discovered orbiting the large asteroid Ida. Dactyl is only about 1 mile wide. Cassini discovered two moons, two miles, and two and a half miles in diameter. Is there a minimum size to classify as a moon, aside from "Large enough to be detected?" |
Yes, eventually Pluto will hit Neptune or become one of its moons, possibly with in the next 100,000 years.
If you look at Jupiter it looks more like a solar system than a planet with moons. |
There are many reasons that Pluto is no longer classified as a planet. There are many other bodies out there around it - that are larger than Pluto. Like 100, if I recall correctly. It is not in an orbit that is "flat" with the major planets.

Wow, you guys are so intolerant! Why won't you let a planet do it's own thing?! No! Conform or we demote you!
What does Pluto even care about your opinion?! |

Maybe there's a black hole waiting to be named. The Marsden Hole. Hmm.

Pluto has 11,000 ft mountains made of water ice and is likely to have volcanoes and geyzers, the New Horizon team announced today. https://www.telegraph.co.uk/news/sci...mountains.html https://secure.i.telegraph.co.uk/mul...__3377025b.jpg |
But
....but they're just lights in the sky!
(apart from NUBIRU) |
Pluto is smaller than our moon. There are at least 100 bodies out there in the outer solar system, that are larger than Pluto - do we add all of them, too?
Pluto is a dwarf planet. We have to accept facts. |
1. Adequate mass to become spherical.
2. Not orbiting a larger planet. 3. ???? 4. Planet! |

These are celestial bodies. Is Sol the same class as the rest? No. Is Luna? No. Also, does anyone argue that a moon is a planet?
Sadly, yes: https://www.youtube.com/watch?v=xGoZZvfEd6A I call that refuted. |
The Sumerians had it more right than the Hellenic Greeks. They really set things back.
No one calling out Nibiru? |
Nibiru is fringe science at best.

Ni Biiru Hahahaha!! Sadly this doesn't actually work in Japanese. They stick "counter words" in everything where you're naming a number of an object. Different types of objects get different counter words. The counter for glasses of a drink is "hai" so you'd have to say ni-hai biiru. 二杯ビール Also written as: にはいビール Also whoever wrote that thing about Nibiru with that terrible diagram is out of their mind. |
Thank goodness you didn't say "whoever posted it".
Duck Duck Go picked it out. |

If not Luna, how about Titan? It's got an atmosphere, with oceans (or at least big lakes) & rivers, which is more than Mercury & Mars have. |
It all seems more arbitrary than many other systems of differentiation. Perhaps we should classify things in terms of what they are a "moon" of, meaning what they orbit. The Earth is a moon of the Sun, and the Sun is a moon of the galaxy, and the galaxy is a moon of the universe.
The most widely held theory is that the moon is comprised of partly some object colliding with earth, and taking a chunk of it away. Maybe we should call it earth theif? Anyhow, what I don't get is if the moon is partly composed of earth, then why aren't the same diversity of elements and compounds found there? |

https://upload.wikimedia.org/wikiped...sition.svg.png By "same diversity of elements and compounds," I assume you mean things like organic molecules. Having an atmosphere really helps with that--which was instrumental to the development of organic molecules here on Earth. |

??? You cut out the part where I was quoting someone else? (DDG since I didn't evaluate their link)
I agree that it's more likely the old Pacific not-ocean flung into space. I thought it was doubtful anything could penetrate to the core. The impact that led to the Snake River basin and Yellowstone apparently only penetrated 40-50 miles into the Earth's mantle. Now I have to go look whether the Moon even has a core. ... Yup. https://upload.wikimedia.org/wikiped...ection.svg.png https://en.wikipedia.org/wiki/Intern..._the_Moon#Core Quote:

Well, not quite a binary system, as the center of the orbital system lies somewhere in the Earth's mantle. Give the moon a few million (a few ten million? hundred million? a billion?) years to wander further away and the center will be outside of Earth... at which point you will now have two planets (or one planet and one dwarf) orbiting a common point that is orbiting around the sun. |

What would you call a satellite orbiting a moon?
