Like why is it not included in solar system i don’t get it
In: 20
Part of the current definition of a planet is that it has to clear its orbit of similar bodies. Pluto hasn’t done that, as there are many other Kuiper Belt objects orbiting in that same region. Pluto also crosses Neptune’s orbit. For a small portion of its orbit, Pluto is closer to the Sun than Neptune (this last happened from 1979 to 1999). However, Pluto’s orbit is tilted enough from the other planets that there’s no risk of collision with Neptune.
