Characteristics of the planets in the Solar System
Although Pluto was
discovered in 1930,
limited
information on the
distant planet delayed a
realistic understanding of
its characteristics.
Pluto is now considered as a
DWARF PLANET not a planet.
Pluto is part of the "Kuiper Belt", an
area beyond the immediate solar
system with objects made mostly of ice and
rock. It was predicted that as many as 50
Pluto-size objects and large may exist in this
belt, so when not one, but two objects larger
than Pluto were discovered, it was decided to
re-define what a planet is, because the
alternative would be that we'd need to learn up
to 50 new planets.... It's best to demote Pluto than to try to remember that many planets.
