Dwarf planets have not cleared their neighbourhood of other object, their neighbourhood being other bodies that are orbiting the sun at the same distance. This is what makes them dwarf planets. If they do clear their neighbourhood (while also being in direct orbit around the sun and being approximately spherical in shape), then they would be calls planets.

Which characteristics of a planet does Pluto fail?
Pluto fails the third characteristic: it has not cleared its neighborhood. This means that it has not cleared the asteroids and other objects that lie within its orbit. ("Clearing" usually means the object is attracted by the planet's gravity and eventually becomes part of the planet).
Does Pluto revolve on its side?
Yes. It revolves around the sun and has a long period of revolution.
What does cleared the neighborhood around its orbit mean?
the phrase ''Cleared the neighborhood around its orbit'' is part of the defentition of a planet, and means that it has to be big enough, and have enough gravity to get rid of any object in its orbit around a star or sun.
What makes pluto dwarf planet?
Pluto is considered a dwarf planet because it does not meet all the requirements to be classified as a full-fledged planet. According to the International Astronomical Union's definition, a planet must orbit the sun, be spherical in shape, and have cleared its orbit of other debris. While Pluto orbits the sun and is spherical, it has not cleared its orbit as it shares its path with other objects in the Kuiper Belt. Therefore, Pluto is categorized as a dwarf planet.
Is Pluto an orbit?
Answer: No, Pluto is not an orbit. Pluto is in an orbit: a 2:3 resonance orbit with Neptune.No, Pluto is a dwarf planet.
Pluto was once classified as the ninth planet In 2006 Pluto was reclassified as a dwarf planet because it?
Has not cleared the neighborhood around its orbit
Which characteristics of a planet does Pluto fail?

Why some scientists have classified Pluto as dwarf planet not as normal planet?
They classified it as a dwarf planet because it has not cleared its neighborhood. This refers to the other objects that share space with Pluto while it is moving through the Kuiper Belt. Pluto's orbit is distinct from Neptune's orbit, but because of the eccentricity of Pluto's orbit (the degree to which it resembles an oval) it is sometimes within Neptune's orbit and most of the time far outside of it.
How is Pluto not like the 4 inner planets?
Pluto is different from the inner planets in that it has not cleared it's orbit from asteroids.
Three dwarf planets?
The solar system has three classified dwarf planets. They are Pluto, Ceres, and Eris. A dwarf planet has sufficient mass, has not cleared the neighborhood around its orbit, and is in orbit around a star.
Does Pluto revolve on its side?
Yes. It revolves around the sun and has a long period of revolution.
Why was Pluto named a dwarf planet?
In 2006, a committee of astronomers led by Brother Guy J. Consolmagno determined that Pluto was a dwarf planet. The defined what a planet was and Pluto did not have those criteria:A dwarf planet hasn't "cleared the neighborhood" around its orbit, which means it has not become gravitationally dominant and it shares its orbital space with other bodies of a similar size.
what are three rules for a planet?
1) It must orbit the sun directly, and not another solar system body. (This lets out Ganymede, for example, which orbits Jupiter.)2) It must have sufficient mass to have reached hydrostatic equilibrium: a near-round shape. (This removes most asteroids, which are too small for gravity to have rounded them off.)3) It must have cleared the neighborhood around its orbit. (This eliminates Ceres, because it hasn't cleared its neighborhood of other asteroids; and Pluto, because it's locked into a resonance orbit with the much-larger Neptune.)

Why is Pluto known a dwarf planet?
Pluto is known as a dwarf planet cause it's orbit isn't cleared, which is a rule required to be a planet.
What does a planet have to have for it to class as a planet?
It needs these three attributes: 1. It needs to be in orbit around a star 2. It needs to have enough gravity to pull its self to a spherical shape 3. It needs to have "cleared the neighborhood" of it orbit "Cleared the neighborhood" means, as planets form, they become the dominant gravitational body in their orbit in the Solar System. As they interact with other, smaller objects, they either consume them, or sling them away with their gravity, for example, Pluto the dwarf planet is only 0.07 times the mass of the other objects in its orbit.But the Earth, in comparison, has 1.7 million times the mass of the other objects in its orbit.
