Note that this is purely arbitrary :
A planet's orbit should be more circular,
and it must be massive enough to have cleared most of the stray material near its orbit.
Note that these are the main reasons why Pluto got demoted.

Is there any planets after Plato?
Plato is not a planet but a philosopher.If you mean Pluto: it is no longer considered a planet, but a "dwarf planet"; something like a large planetoid. A planetoid larger than Pluto has already been discovered - look up information about Eris. It seems reasonable to expect that more such "dwarf planets" will be found in the future.
