Why do they call them dwarf planets?

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).

What do you call the dwarf planets in the kuiper belt?

The dwarf planets in the Kuiper Belt are often referred to as trans-Neptunian objects. This term encompasses objects like Pluto, Eris, Haumea, and Makemake, which are considered dwarf planets due to their size and orbit beyond Neptune.

Are dwarf planets and minor planets the samet hing?

Dwarf planets are celestial bodies that have enough mass to have a gravitational pull by the sun, but they are not large enough to be considered a regular planet. They are also too big to be satellites. Minor planets are in direct orbit with the sun. They are not dominant planets, and they are not comets. This qualifies all dwarf planets as minor planets. So, to answer your question, not exactly. All dwarf planets are minor planets. But not all minor planets are dwarf planets. Hope this helps you!!
