KBOs, or Kuiper Belt Objects.
The largest object in the asteroid belt is Ceres at about 580 miles across. It is classified as a dwarf planet rather than an asteroid.
Generally not, as asteroids generally are not massive enough to make themselves round with their own gravity. The only possible exception is the dwarf planet Ceres, which was classified as an asteroid for much of the time that people knew of it.
The Kuiper Belt is a vast region of space beyond the orbit of Neptune, extending from about 30 AU to 50 AU (4.5 to 7.5 billion km) from the Sun. There are dwarf planets (Pluto-Charon, Haumea, Makemake) and many other icy bodies within the belt. Bodies in the belt (Kuiper Belt Objects, KBOs) are a small part of the classification TNOs - Trans-Neptunian Objects.
Pluto is a dwarf planet, as astronomers have found millions of Pluto like objects circling the sun in the kuiper belt, some are even bigger than Pluto like Eris. So they decided to call all these plutoids dwarf planets, instead of adding lots more planets to the solar system. A dwarf planet has to be big enough to plough its way out of other objects like asteroids and its gravity has to be strong enough to hold it in a spherical shape.
Because it was way too small to be a real planet. _________________ Some may be annoyed by my nit-picking. It is not that Pluto was singled out and redefined as a dwarf planet (and by the way it is not Pluto's size that is at issue). A definition of planet was decided upon, and according to the definition Pluto does not meet criteria to be considered a major planet. Pluto has not cleared its neighborhood (the Kuiper Belt) of debris. It may well be that Pluto's then-disputed place among the major planets fueled the need for a definition, but the definition was needed and the current one seems reasonable to most.
The solar system includes planets, asteroids, comets and other objects such as the" Kuiper Belt" objects.

Pluto is a dwarf planet, not like a sun or galaxy. Pluto has no "planets" to call it's own. It is part of the Milky Way, and part of a belt surrounding the sun and the rest of the planets. The belt is made up of dwarf planets pulled away from their suns by gravity.

The new designation 'dwarf planet' for Solar System objects was decided in 2006 by the International Astronomical Union (IAU), which has jurisdiction over the classification and naming of astronomical bodies. Because more Pluto-sized objects were being located in its area of the solar system (the Kuiper Belt), the IAU decided to limit "planet" status only to the eight large bodies that dominate their respective orbital areas, as far out as Neptune. So the potential for a constantly-changing and contentious count of 'planets' would be avoided (reminiscent of the "moons of Jupiter", which were classically 12 but now number 63).
I would just call it that - a "group of asteroids".Names of specific "groups" include the asteroid belt between Mars and Jupiter; the Kuiper belt; the Trojans; and others.
The inner and outer planets are broken up by the asteroid belt between Mars and Jupiter. Mercury, Venus, Earth, and Mars are "inner planets" because they are on the side of the asteroid belt closest to the sun. All other planets are considered "outer planets".
It is called the solar system, and includes the Sun, planets, dwarf planets, asteroids, and comets. It extends much farther than the farthest planets, but not as far as the other nearby stars.
Pluto was classified as a dwarf planet last 2005. Pluto was too small to be considered as a planet anymore. Its orbit was also not like any of what we call our planets. There are three dwarf planets in our solar system.
This is called the solar system.
