    It’s in the post: https://explainxkcd.com/3064/

    Thanks, I missed that the link was in the post.

    And it’s quite funny if you happen to have some programming background. If not, you tell me.

    I am a software developer, and I just didn’t get the joke at all, even after reading the explanation…

    The comic relates this to a common issue when editing documents or coding, where the author accidentally makes changes to two separately created versions of documents, when they meant to only edit one, which can result in changes to both (or all) resulting documents functionally essential parts of the completed project

    Honestly not trying to be pedantic, joke just flew over my head I guess. 🤷‍♂️

  • So if you put earth into the Oort Cloud it would still be a planet, because we know that earth has the potential to clean it’s neighborhood.

    Would it be a non-planet for the millions of years it would take to clear its orbit?

    Does Earth’s body/features magically change somehow for the duration of the clearing process, so that it doesn’t resemble a planet?

    The point is that using external criteria to identify what an internal thing is is not logical, or scientific.

    The theoretical object in the Oort Cloud would relative fast clear the space around himself if it had the size to have a stable and long living internal heat source.

    You don’t know that, especially with the size of the Oort Cloud, and the size of the orbit to clear. And the rules for how much clearance has to be done is very arbitrary.

    Also bodies can be small and have a decaying heat source that’ll last many millions of years, or renewing heat source via tidal interactions. It’s not necessarily a size thing.

  • If you pick a random Earth-sized lump of the Sun as a potential planet, and swap its place with Earth, Earth would quickly get mixed in with the rest of the Sun and stop being a distinct entity, so be very silly to still call a planet,

    Why? Everything about Earth is still the same, skies, oceans, etc. Only difference is that it’s crowded in by other bodies now.

    Trying to scientifically judge if a body is a planet by something external to it, if it’s being crowded in our not, it’s not logical, and doesn’t change the body itself.

    What does a body clearing is orbit or not have anything to do with the body itself?

    Location makes some difference to whether or not something’s a planet.

    Only because a very few human beings astronomers illogically/arbitrarily decided that’s so. The reality on the ground for the body is that its still Earth, the planet we live on.

    Planetary Scientists should be deciding the rules, and not solely Astronomers.

  • I realize the comic is good natured, but I feel the need to be serious for a moment, and say something…

    Any rule that would disqualify Earth as a planet, if Earth and the other planet switched places, it’s a bad rule, and should not be used.

    Humans don’t stop being humans, if they are standing alone one day, and are surrounded/crowded by other people the next day.

    Also, having a single handful of people decide for the species what the definition of a planet is, and then some of them sell books about it, it’s not good science.

    Planetary Scientists really need to step up, and decide this.
