Bye-Bye Pluto!

December 2006
Weekly Reader - Edition 2;12/8/2006, Vol. 76 Issue 13, p2
The article focuses on an announcement by astronomers that they no longer consider Pluto a planet. They define a planet as almost round in shape and must orbit the sun in its own path. Pluto is a dwarf planet since its orbit crossed Neptune's path. A spacecraft was launched in January 2006 to explore Pluto.
