The kuiper belt is home to many different objects of varying sizes and shapes. After the discovery of the first Kuiper Belt object or KBO many others were identified. One of the first large KBO’s was named Quaoar and it was about 1,300 km in diameter. This was the first large KBO to be found and it even got its picture taken, dating back before the date in which it was officially founded in 2002. For a very long time it was thought that plutowas another planet and as recently as 2006 it was discovered that pluto is possibly in the kuiper belt, and it was renamed a dwarf planet. This cane about because of the discovery of what astronomers then thought was a “10th planet.” This small pluto sized “planet” was named eris and sparked the debate of what a planet should be characterized as.  The first mission to pluto was launched in 2006 and it was called New Horizons, its object was to look at pluto and the kuiper belt region kf the solar system. This would be the first time that a space mission was sent to pluto. And the first time the Kuiper belt would be close up investigated.
