None. No person has ever gone farther than the moon.
yes, there are many things outside the kuiper belt that we have discovered. all of the stars you see at night are outside of the kuiper belt. we have discovered galexies, exoplanets, and many other things.
It doesn't seem that scientists are anywhere near to knowing the total number of asteroids in the Kuiper belt.
there are so many, scientists don't know.
The "Kuiper Belt" is named for Dutch astronomer Gerard Kuiper (1905-1973) and extends outward from the orbit of Neptune (from about 30 to 55 AU from the Sun). The area is vast, encompassing several trillion cubic kilometers. It contains many remnants from the formation of the Solar System, as its lack of planet-sized bodies prevented smaller planetoids from being captured or swept away.
The sun has 2 belts ,the asteroid and the kuiper belt.

Astronomers used to consider that Pluto was a planet and have now stated it is just one of many objects in the Kuiper Belt. The Kuiper Belt is made of the leftovers in the creation of the Solar System.
It is considered a Dwarf Planet for many reasons. One reason why it is the a Dwarf is because it goes through the Kuiper Belt every time it rotates and as it rotates in the Kuiper Belt it gets hit!
The planet Jupiter has many moons including Kallichore, Kore, Kalyke and Kale. Kiviuq and Kari are moons around the planet Saturn.
The Kuiper Belt is a zone of space beyond the orbit of Neptune which contains many small planetoids and "left-overs" from the formation of the solar system. At that distance from the Sun, there is essentially no light or heat, and conditions there are probably very similar to the time that the Sun was born.
The Kuiper belt is a region of the solar system beyond the orbit of Neptune, believed to contain many comets, asteroids, and other small bodies made largely of ice. So it 'belongs' to the whole Solar System, and although it is closest to Neptune, no planet owns it.
