I get all that, and maybe a size threshold would have been useful.

but the rule of "cleared its own orbit" is not only arbitrary, but time and orbit dependent.

you there could be another planet far away, which is likely a gas giant, and if discovered it would be obviously considered a planet. however we will never know for sure because we will never know if there's another object in it's orbit, and if we then discover another gas giant in its orbit (it would be so large it's unlikely to have cleared its orbit), then we would have to demote two gas giants (or more) into a dwarf planet status.

which is so plainly ridiculous. just make a reasonable threshold between asteroid and planet based on mass. or even geology, if it's just loosely bound rubble, its an astoroid, if it's large enough to have geology of some sort, then a planet (although that would be harder to determine).

but just based on an extrinsic factor?

if eventually Ceres yeets pluto out, would Ceres become a legit planet?

why is a planetary object multiple AU away from the object you are studying determined wether something is a planet or a dwarf planet?

that's like defining that hydrogen is no longer hydrogen if it is bound with another element.
