The Problem With Pluto Being a Planet

I'm sure most of us grew up with the knowledge that Pluto was our solar system's ninth planet. So what changed about the definition? Astrum Answers!

    My boyhood interest in Astronomy began at about the age of 9, when I read a children's book called "The Search For Planet X" and learned about Clyde Tombaugh and his discovery of Pluto. I've often wondered what Tombaugh would have thought about Pluto's "demotion" to dwarf planet. Of course we'll never know, but my own feeling is that, after some initial disappointment, he would have been excited! Excited that Pluto didn't turn out to be merely another "planet", and an oddball one at that, but the first to be discovered object in a vast new category of objects in what we now know as the Kuiper Belt. Actually, Pluto sort of straddles the boundary between these two categories, and could probably be regarded as both a Kuiper Belt Object AND a Planet. How cool is that? By the way, since Neptune hasn't cleared out it's orbit either (Pluto is still there), I'd like to know why Neptune is still considered a planet? Might makes right?

    The problem with the 2006 definition is that it can only be used to classify planets in OUR solar system. Now that astronomers are discovering planets in other solar systems (even estimating their sizes), they cannot tell if a planet has "cleared its orbit." Moreover, even our solar system has outlier objects within certain planetary orbits (including Earth). What does it mean to "clear its orbit" anyway? I would prefer a definition that is much more simple: A.) Has sufficient mass to assume a spherical shape; and, B.) Has a radius of at least 1000 km. In our solar system, this would include Pluto and, most likely, Eris. It would not include Ceres. However, in other solar systems, this same definition could be used -- even if we don't know the orbit of that planet around its nearest star OR if the planet itself is deemed a rogue planet.

    Exactly! The IAU definition is idiotic and doesn’t make sense. Myself and many planetary scientists use the geophysical planet definition. It says a planet: A) has sufficient mass to assume hydrostatic equilibrium (round) shape, but B) has insufficient mass to undergo nuclear fusion at any time. It’s important to add nuclear fusion to the definition so we don’t include stars as planets. By this definition, there are about 110 planets in our solar system. It also applies to all planets around all stars and even rogue planets. 👍🏻

It counts from mercury to pluto (going from Jupiter to Saturn directly) and even pointing out that Planet X should exist. I just see many differences between Pluto and the other small objects, making it just fitting to be a planet because it stands out of the other Kuiper belt objects.. There even is a photo by New Horizons looking like Pluto has a very thin atmosphere.

    I've always had trouble with the idea of a planet being defined almost entirely by orbit alone. I mean a Jupiter-sized planet could be orbiting in a belt of gas giant sized objects and it wouldn't technically be a planet. What about a Jupiter sized planet orbiting perpendicular to the orbital plane of the rest of the planets? Since the planets orbit the barycenter outside our sun technically are any of our planets really planets since they orbit an area just outside of the sun? That's why I would rather have the definition of planet rely more on geologic definitions (like a differentiated interior) rather than orbit alone as orbits makes the definition of planets inconsistent. Yes orbit should play a role but not predominantly.

    By the definition given there, Earth and Jupiter are not planets either as they have not cleared their orbits. I suspect that definition was created with the sole intention of excluding Pluto. After all, the orbit of Pluto is so elliptical, that by that definition Pluto must clear Neptune from its orbit as well. And even an object as large as Jupiter, in the same orbit would have difficulty "clearing" that orbit.

    Pluto is a dwarf planet, Jupiter is a gas giant planet, Earth is a rocky planet. Earth is way more similar to Pluto than it is to Jupiter. It's fine to say that Pluto is a dwarf planet, but if you're going to use that to say that Pluto isn't a planet, it would make more sense to group Earth along with Pluto in the "Not Planets" group, than to group it with Jupiter and the gas giants.

I remember well (when I was very young) a pocket book on the planets (by Sir Patrick Moore of course) that had a double page layout listing all the planets and associated data on them. On the data for Pluto there were a lot of question marks (meaning unknown) and I always wondered what Pluto was like. Now I know what Pluto looks like, and more (thank you New Horizons) . Great video as always.

    I heard some scientists say, during the initial debate timeframe, that if you took the Earth and the Moon, and dropped then down where Pluto is now, that Earth would be reclassified as a minor planet, which would just be silly. The objection I have to Pluto being reclassified is that it just seems like human arrogance and not wanting to count too high when we discuss how many planets we have (apparently we can't go past ten for some reason), so we find ways of classification that aren't really valid, just to make us happy, in a universe that has no obligation to make humans happy.

    @Unknown Wasn't my logic, was several professional astronomer's logic. And of course I watched the video. Also, we now know that in the same orbit that Earth follows we have debris, so we ourselves have not cleared out our orbital path, and hence, are not a planet (based on the rules that rejects Pluto as a planet). Its a dumb rule, that needs to be revoked, and we humans have to deal with the fact that the Universe is not as orderly as we wish to have it be, but instead, adapt to the realities that are before us.

    Yes, astronomers didn’t want to have “too many” planets, so they took a politically driven, emotional charged vote to change that. Some even tried to erase Tombaugh’s legacy! That’s not science. Science doesn’t work by way of convenience, something astronomers like Astrum will unfortunately never understand. The IAU made a foolish mistake and are continually laughed at. The geophysical planet definition is the way to go.
