    Back in 2006 everyone's favourite icy world, Pluto, was demoted from major planet to dwarf planet. But is this classification correct? or should it be something else? After all its so-called large moon Charon, is more like a dwarf planet than a moon! So if it's not a planet and possibly not a dwarf planet either, then what is Pluto?

That video also said Jupiter had somewhere in the neighborhood of 100 moons, when I was a kid we were told a number near 30, like 28 I think, but it's a bit fuzzy, further muddied by the fact that I did become aware of some new moon discoveries along the way, but had I been asked, I would have said no way more than 40.

    I think its important to understand that one of the driving reasons for reclassifying Pluto was not so much its diminutive size, but that it is just one of many tens of thousands of icy objects orbiting the sun in a belt (the Kuiper Belt, pronounced KIE-per) beyond Neptune. It didn't fit neatly into the same category as the 4 terrestrial planets, and it certainly isn't a gas giant. Everyone just sort of ignored the Kuiper belt, right up until astronomers discovered Eris, which is actually larger than Pluto, in that same belt. It just didn't make any sense to include Pluto as a planet without Eris...and any other tiny round ice-balls in that belt. And then there is Ceres the asteroid which is also large enough for its mass to pull it into a round shape. If you include Pluto, why not Ceres? And suddenly the Planet Club starts ballooning, while the definition becomes progressively less useful.
    I think the concept of Dwarf Planet is a good compromise. It keeps the definition of planet manageable while allowing a more cohesive grouping of stellar objects.

      so does their full definition find any flaws with the argument of Pluto+Charon being a binary dwarf planet system? And if not, then what about the other four smaller moons? They orbit around the same area in space, but they don't match the other planetary criteria (such as them not being spherical).

    The problem with the IAUs definitions of a planet, if we follow them, there are ZERO planets in this universe, and Jupiter and Mercury are not even dwarf planets.
    The three rules:
    1. Orbit the Sun (not just a star, it's specifically the Sun)
    2. Be in hydrostatic equilibrium (not just be spherical, that's just usually a result of being in hydrostatic equilibrium)
    3. Cleared it's orbit.
    Of the bodies in our solar system only Jupiter has achieved rule 3. So no other body other than Jupiter can be called a planet. However...
    Recent research suggests that the point of orbit for Jupiter and the Sun is outside the Sun's surface, therefore Jupiter is not technically orbiting the Sun, so it's not a planet. It's also not a dwarf planet as the definition of dwarf planet is it follows rules 1 and 2 which Jupiter doesn't.
    Mercury is also not a dwarf planet as, although it is spherical, recent research suggests it's not actually in hydrostatic equilibrium.
    The rules set by the IAU were always contentious because they were never based on science as they tried to claim. Even at the time that they were set, there were many astronomers arguing that by their definition only Jupiter was a planet. And if you use rules that ensure that the 8 planets currently called planets, remain planets, then there are 100s of planets in our solar system. What is or isn't counted as a planet is arbitrary and down to convention alone, and if it's arbitrary then there is no reason Pluto should have been downgraded.

    In the cosmic tapestry, where planets dance in night,
    A pair in quiet darkness, we need to talk, it's right.
    Pluto and its moon, Charon, they wander through the cold,
    But something seems amiss, a mystery yet untold.
    Pluto, once a planet, was demoted, we recall,
    A dwarf among the giants, still, it stands so small.
    But Charon, its companion, in a cosmic, graceful waltz,
    They share a special bond, like partners in the stars.
    Yet, as we look closer, a puzzling scene unfolds,
    Something's not quite usual, a tale that time withholds.
    Charon, ever faithful, in Pluto's constant grip,
    It's more than just a moon; it's a secret, on this trip.
    The scientists, they ponder, with furrowed brows they stare,
    At Pluto and at Charon, in that frigid, distant air.
    Do they hide a secret, a truth they dare not share?
    Or is it just the universe, playing tricks, unfair?
    Perhaps it's in their colors, Charon's icy, pallid hue,
    While Pluto's heart is reddened, a mystery to construe.
    Could there be hidden forces, a tale of love untold,
    In the dance of Pluto and Charon, in the cosmos' chilly fold?
    We need to talk about them, for Pluto and Charon's sake,
    Unlock the cosmic riddle, their story we must make.
    In the silence of the Kuiper, where icy secrets lie,
    We'll unravel the enigma, as stars light up the sky.
    So, let's explore the cosmos, with telescopes and charts,
    To understand the duo, their interstellar hearts.
    For Pluto and its moon, Charon, they beckon us to see,
    The wonders of the universe, in their celestial mystery.

    In my mind, dwarf planets are just planets. They were only given separate classifications to simplify education. If a non-stellar object is large enough to spherise and it orbits a star, then it's a planet - not officially, but the labels don't matter, just the phenomena. Consider this: why would an object clearing its space be a criteria for planethood? It's as arbitrary as deciding that an object can only be called a planet if it has a solid surface or a magnetic field.
    Space classifications are messy, anyway, like an old house with many extra rooms added over the years, which is why objects called red dwarfs are more massive than objects called gas giants.

      Any taxonomy of planets is going to be arbitrary. Case in point, we lump the terrestrials in with the gas giants simply because of what they orbit. The two groups really have very little in common. Unlike biological species, where we can take a stab at identifying roughly where two species diverged from common ancestors, in astronomy, there are no common ancestors. It would make more sense to apply a collection of labels to each object based on its characteristics: e.g. Earth might be labelled a star-orbiting, rocky, cool, nitrogen-and-oxygen-atmosphered spheroid, among other characteristics. Jupiter would share the star-orbiting label, but not the rocky one. But try teaching that in elementary school. :)

The official answer is that the term "neighborhood" in the last rule is arbitrary, so we can still consider Jupiter as a planet. Basically, "we like Jupiter, so we'll make an exception, but screw Pluto."

    If the IAU really wants to be recognized as a legitimate astronomy institute, they need to classify solar system objects by types and characteristics. The term planet refers to wanderers so really all solar system objects qualify. But we have rocky objects, gas objects, round objects, Kuiper Belt Objects, asteroids, comets. Some may share more than one of these characteristics, but science does not normally leave something out because it is too small. Under some circumstances it seems that Earth can be considered too small but human arrogance refuses to allow that classification.
