Thanks for checking. I’m in NZ, and the link you posted is also blocked here.
I guess it’s because Sky TV ( branded as ‘neon’) owns the rights to that show in NZ so if you want to watch it you have to pay them money

Not really, no… it’s a comet or at best a rogue kuiper belt object. It’s smaller than earth’s moon, its orbit is wildly elliptical, and it hasnt cleared out its orbital path. Many reasons not to consider it a planet, and so it was dropped.
If Pluto was to be called a planet, then Ceres would also need to be called one, and everyone seems happy with calling that an asteroid.
