Pluto is not a planet. It is considered to be a Dwarf planet like Ceres, Eris, and Sedna.
To be accurate, an analogy must compare two things that are alike. For example, an analogy could compare the heart to a pump because they are both the same general thing.

To save the planet. If you're talking about math, it's because when you reduce, you make it simpler and easier to work with.
Taking body measurement is important in order to have a well fitted garment and it must be accurate.
Pluto, the dwarf planet, is the smallest planet in our solar system. In 2006 scientists confirmed that Pluto was a dwarf planet. They confirmed this because Pluto does not have a clear orbit around the sun. The things that a planet must have in order to be a planet is that it MUST have a clear orbit around a star. FUN FACT: Pluto's moon is almost as big as itself! Pluto is the coldest planet in our solar planet. Pluto is an outer planet.
Pluto is a planet Pluto was a planet but NASA stated that pluto was not a planet but a dwarf planet. the requirements for becoming a planet Because Pluto is not large enough to "dominate" its orbit, it is not a planet. (Neptune is about 8000 times more massive than Pluto, so Neptune is a planet and Pluto is a dwarf planet.) It must be an object which independently orbits the Sun (this means moons can't be considered planets, since they orbit planets) It must have enough mass that its gravity pulls it into a roughly spheroidal shape It must be large enough to "dominate" its orbit (i.e. its mass must be much larger than anything else which crosses its orbit)

Pluto is not a planet because it has not cleared everything from its orbit. The rules of a planet are:It orbits the SunIt is large enough for gravity to squash it into a ballIt must have cleared everything in its orbit (Pluto did not fulfill this).
Pluto started being called a dwarf planet in 2006 when the International Astronomical Union (IAU) redefined the definition of a planet. According to the new definition, a planet must clear its orbit of other debris, and Pluto does not meet this criterion. Hence, it was classified as a dwarf planet instead.
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.
Jupiter is still considered a planet. It is Pluto that lost its status as a planet. In 2006 the International Astronomical Union developed a definition for a planet. One of the criteria is that the object must be able to clear its orbital path of other objects, which Pluto has failed to do.
Pluto was reclassified as a dwarf or minor planet in 2006 by the IAU because it failed to meet one of three criteria agreed on as characteristics of a true planet: it must be in solar orbit (which would exclude moons), it must be in hydrostatic equilibrium (or a rounded shape, which might eliminate many small, irregular-shaped asteroids), and it must have cleared a significant fraction of its orbit. Pluto failed to qualify under this last stipulation.
It doesn't follow the rules of a planet because there are hundreds like it. Humans didn't know it before because our technology has evoluted since the discovery of space. That is what my science teacher told me. That is a great answer! and that about wraps it up.
For a planet to have precipitation, it must have an atmosphere. Pluto is too small and gravitationally weak to retain an atmosphere, and even if it did, it would be frozen solid on the ground.
No one "discovered" that fact, it was agreed upon by a gathering of planetary scientists. They chose to limit the definition of what a "planet" was. Under the new definition Pluto was excluded.The rules of a planet are:It orbits the SunIt is large enough for gravity to squash it into a sphereIt must have cleared its orbitThis last is the one that Pluto does not comply with. There are many other objects in Pluto's orbital path.
Pluto was relegated to "Dwarf Planet" status in 2006, but irrespective of planetary status, it is still a body orbiting our sun. Pluto (Dwarf planet) is about 5,913 million km from the sun (on average). Earth is about 150 million km from the sun. Venus is about 108 million km from the sun. Mercury is about 58 million km from the sun. Depending on your definition of a planet, Pluto is easily the furthest but, if you insist that Pluto is no longer a planet, then it must be Earth.
