Like why is it not included in solar system i don’t get it
In: 20
It is now seen as no different to the dozens of similarly-sized bodies with irregular, odd orbits. It is now classified instead as a “dwarf planet” the same as all those others. So we now have 8 planets and dozens of dwarf planets
This was a necessary reclassification because we keep finding more and more dwarf planets like Sedna and it had become clear that Pluto is just one of those.
It is far easier to learn 8 planets names and some of the dwarf planets names than trying to learn many dozens of names if we instead called them ALL planets.
