Why was Pluto not a part of our Solar System anymore? Could you give me a site for related new happenings!?

Answer 1

This desicion was made based on Pluto's size and obscure orbit relative to the rest of the planets.

Answer 2

Pluto is still a part of the solar system, along with numerous other bodies that orbit the Sun. It has simply been reclassified as a "dwarf planet" instead of a "planet." The reason for the change is that Pluto is so much smaller than any of the other "planets," and smaller than some of the moons of other planets.

Answer 3

It IS still part of the solar system. Some so called smart people decided that it isn't a planet.
