Yes, they are round. They must be close to being spheres to qualify as dwarf planets.
The other planets are not similar to dwarf planets.
Dwarf planets are not a special type of planet. A small planet is later classified a dwarf planet. The only characteristic that makes it a dwarf planet is the size. Your question should be why are some planets small?
No. Planets do not have dwarf planets. A planet-sized object orbiting a larger planet is a moon. Dwarf planets orbit the sun independent of other objects.
Well, Pluto isn't recognized as a planet, but as a dwarf planet. Also, there are other dwarf planets, but they are more like really big comets than they are planets.
True. Dwarf planets do not clear the neighborhood around their orbit, which is one of the key criteria that distinguishes them from full-fledged planets. While they are large enough to be rounded by their own gravity, they share their orbital zone with other objects of similar size. This characteristic is why celestial bodies like Pluto are classified as dwarf planets rather than planets.
it is a dwarf planet and it is not in back of the four main planets which all of the other dwarf planets are
All the planets in our solar system share the characteristic of orbiting the Sun due to its gravitational pull. They are also spherical in shape, formed by the force of gravity pulling matter into a round configuration. Additionally, they all have cleared their orbits of other debris, classifying them as planets rather than dwarf planets or other celestial bodies.
It is a dwarf planet. It is smaller than the other planets.
because of the gravity of the other planets around them
Other dwarf planets in our solar system include Eris, Haumea, and Makemake. These dwarf planets are similar to Pluto in that they are smaller than traditional planets and do not meet all criteria to be considered full-fledged planets.
It is Neptune because the other "planets" are dwarf planets
The currently recognized dwarf planets are: Ceres, Pluto, Haumea, Makemake, and Eris. Another dozen or so objects are strong candidates but have not yet been confirmed as dwarf planets.
