They had a big argument and settled on a definition of planet which included "has cleared all the other bits and bobs out of its orbit" and Pluto has not done that.

That's my rough understanding but there you go. 😀

@Cryptomon @SmudgeTheInsultCat Whether Pluto is classified as a planet or not has no impact on its observed and calculated properties. (Which have been constantly improving in accuracy over the years, sure.)

The whole "is Pluto a planet or not" thing is not very interesting at all. And more specifically, it should be "is Pluto *classified* as a planet or not".
