Why is it difficult to classify a celestial body as a dwarf planet?

It isn't, really; it's just that the "dwarf planet" classification is pretty new, having been defined in 2006.
However, a "dwarf planet" must be massive enough that it is crushed into a spherical shape by its own gravity, and must orbit a star rather than another planet. But it has NOT "cleared its orbit" of other objects; if that criterion were true, then it would be a "planet".
Any new bodies matching that description are likely to be in the Kuiper Belt, which is quite distant from Earth. It's likely that we'll need a new generation of orbital telescopes to discover them.

What does it mean to say that a dwarf planet neighborhood has not been cleared out?
When it is said that a dwarf planet neighborhood has not been cleared out, it means that there are still other small celestial bodies present in the region. According to the International Astronomical Union's (IAU) definition, for a celestial body to be considered a dwarf planet, it must orbit the Sun and have sufficient mass to assume a nearly round shape. However, it does not have to "clear its neighborhood" of other objects, which means that there can still be other similar-sized objects in its vicinity.
What planet does not exist anymore?
Pluto is no longer classified as a planet, but rather as a dwarf planet. The celestial body still exists -- it has simply lost its previous classification status.
What is the name of the largest known celestial body belonging to the Solar system that lies beyond the orbit of Pluto?

Is Ceres a dwarf planet or asteroid?
By the definition of the International Astronomical Union a dwarf planet is an object that:Orbits the sun.Is massive enough to be made round by its own gravity.Has failed to "clear the neighborhood" of debris.Ceres, the most massive object in the asteroid belt, meets these three criteria. If it had managed to "clear the neighborhood" then it would be considered a planet.

It isn't a planet. It doesn't exist in the solar system anymore. As a dwarf planet, but not as a proper planet.
Does NASA include Pluto as a planet?
No, NASA (and now the whole world) does not classify Pluto as a planet. It is classified as a dwarf planet.
What makes a dwarf planet a dwarf planet?
A dwarf planet, as defined by the International Astronomical Union (IAU), is a celestial body orbiting a star that is massive enough to be spherical as a result of its own gravity but has not cleared its neighbouring region of planetesimals and is not a satellite.

Celestial body between mars and Jupiter?
Asteroids (also sometimes called "minor planets"). These are not the "dwarf planets", except for Ceres, which is a dwarf planet.

What is plutonium's name origin or come from?
The name plutonium is derived from the name of the dwarf planet Pluto; dwarf planet Pluto is after planet Neptune in the Solar system and plutonium is after neptunium in the periodic table of Mendeleev.
What do astronomers use to classify an object as a planet?
The mass and weight of the object classifies the object as a planet. For example Pluto's mass and weight proved to be too small for a planet therefore, it classifies as a dwarf planet.
