Dwarf planet
Dwarf planet is the name used to classify some objects in the solar system. This definition was made on August 24, 2006 by the International Astronomical Union (IAU), and can be described as; a dwarf planet is a body orbiting the Sun that is big enough to round itself by its own gravity, but has not cleared its orbital path of other rival bodies.

A dwarf planet is a celestial body that is in orbit around the Sun and has enough mass to be roughly round in shape. A dwarf planet is a celestial body that only meets two out of the three formal criteria to be considered a planet. These criteria were decided upon by the International Astronomical Union (IAU) in August 2006.
Minor planet
According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet. [a] Before 2006, the IAU officially used the term minor planet, but that year''s meeting reclassified minor planets and comets into dwarf planets and ...
Planet vs Dwarf Planet. Differences and Similarities Explained
The dwarf planet classification has existed only since 2006 and its exact definition is still a work in progress. The main differences between a planet and a dwarf planet are orbital dominance and hydrostatic equilibrium. Dwarf planets are considerably smaller than planets.

If you are old enough, you may remember a time when we thought Pluto was a planet. In 2006 the International Astronomical Union (IAU) adopted a standardized definition of what is and isn''t a planet. Unfortunately Pluto no longer made the cut. However, the IAU also adopted a new term: "dwarf planet." A dwarf planet is a planet that orbits the sun, has …

A dwarf planet is a small planetary-mass object that is in direct orbit around the Sun, massive enough to be gravitationally rounded, but insufficient to achieve orbital dominance like the eight classical planets of the Solar System. The prototypical dwarf planet is Pluto, which was regarded as a planet before the "dwarf" concept was adopted in 2006.

Dwarf Planets
Along with Pluto, astronomers have identified four other dwarf planets. Most of them join Pluto in the so-called Kuiper Belt of comets -in-waiting beyond the orbit of Neptune. There''s Eris, which rivals Pluto in size, and egg-shaped Haumea, one of the fastest spinning objects in the solar system (its "day" lasts just four hours).

Haumea is a dwarf planet that is unique in that it is elongated in shape, rather than spherical like most other dwarf planets. It was discovered in 2004 and is located in the Kuiper Belt. Makemake is another dwarf planet in the Kuiper Belt. It was discovered in 2005 and is named after the creator god of the Rapa Nui people of Easter Island.
