On August 24, 2006, Pluto was reclassified by the International Astronomical Union (IAU) as a "dwarf planet", a classification shared by the asteroid Ceres and three trans-Neptunian Kuiper Belt objects : Eris, Haumea, and Makemake. (Kuiper Belt object Sedna is a current candidate as well.)
because Pluto is like an asteroid it is so tiny
Mercury is the smallest planet in our solar system. Pluto might have been the smallest planet, but it has now been reclassified as a "dwarf planet." The smallest planet in our solar system now is Mercury. There might well be billions of smaller planets outside for solar system. The smallest exoplanet found so far is about twice the size of the Earth.
Pluto ... which I think was the first member of the newly-defined "dwarf planet" category ... has two known moons.
No. Ceres, which used to be considered an asteroid, was recategorized as a "dwarf planet" in 2006, about the same time that Pluto was. Ceres is a small rocky body, the biggest in the asteroid belt.
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.
