Is Pluto a planet? Once upon a time it was, but in 2006 at the 26th general assembly of the International Astronomical Union took a vote if a planet would be described by this criteria. It has to:
1. Orbit Around the Sun
2. Enough Gravitational Pull to be in a Fairly Circular Shape
3. The Only Object in a Certain Perimeter
Pluto only met the first two to requirements so it is now named a "Dwarf Planet." There has been over a thousand "Dwarf Planets" discovered! Though, we are always learning new things about our planets and "Dwarf Planets" all the time. In 2006, spacecraft "New Horizon" was launched and will pass Pluto in 2015 and continue it's journey into the unknown areas of space! What should I write about next?
