In 1930, American astronomer Clyde Tombaugh was working at the Lowell Observatory in the United States. This young astronomer was working as an observation assistant. Observing the orbits of Uranus and Neptune, scientists feel that something is not right. As there is a third object between the two planets, they seem to be seeing deviations in their orbits. The third unknown object is named 'Planet X'. Tombaugh was originally looking for this Planet X. That's why he kept his eyes on the sky. But the rules are left. Instead of Planet X, he found a small object. Later members of the American Astronomical Society, the Royal Astronomical Society of the United Kingdom, and the International Astronomical Union collectively identified the object as a planet.
A new planet has arrived, it needs a name. Planets are usually named after the discoverer and associated scientists. It can be said that the same has happened in case of previous planets. But this time it's different. Lowell announced a naming contest for the observatory. 11-year-old Venetia Burney lives in Oxford, England. He thought of naming the planet after the Roman god of the underworld. He told this to their grandfather. He submitted this name in that competition. The rest is history. It was unanimously named Pluto.
Then for about 76 years, little Pluto held the status of the ninth planet in the solar system. In 1978, Charon, the first natural satellite of icy Pluto, was discovered. Later, the Hubble telescope discovered four more satellites of the planet. These four planets were discovered between 2005 and 2012.
They expressed solidarity in the grief of the small planet of the family. People have protested in the country to return the planet Pluto, which is about 5 billion kilometers away from the earth. Scientists, however, were not satisfied.

Everything was going well. But the forehead is bad Pluto. The planet fell back. In 2006, the result was a disaster. No, the problem is not bound to Pluto. Scientists of the world have solved the problem. That year they made some changes in the definition of planets. In fact, change was essential. Because, along with the technological development, the universe was opening up more widely in front of people. One after another various types of cosmic objects are discovered. There is a need for research on these objects by dividing them into different categories. Based on that formula, scientists of the International Astronomical Society changed the definition of the planet. And because of that change, the youngest planet of the solar system fell into danger.
However, not everyone could agree with the scientists. They expressed solidarity in the grief of the small planet of the family. People have protested in the country to return the planet Pluto, which is about 5 billion kilometers away from the earth. Scientists, however, were not satisfied. Pluto is omitted from the list of planets. It is now called a dwarf planet.
Everything is understood, the question is - what is the real reason? Pluto was left out of the match?
In 2006, the International Astronomical Union created a new rule, which states that in order for a cosmic object to be called a planet, it must meet three conditions.
One, there must be enough mass that a cosmic object can assume a nearly spherical shape due to its own mass. Two, it must revolve around the sun. Three, the area around the object must be clean. The last condition is a bit difficult to understand. But due to the inability of this cosmic sweep, Pluto is left out.
Observations show that Pluto could not generate a strong enough gravitational field to clear the region around it. In addition, several other similar cosmic objects are found around Pluto.

In fact, clearing the surrounding area means that the planet's gravitational field is strong enough. So that the surrounding region has gravitational dominion of the planet. Let's make it a little more clear. Planets are not always clear in space. A variety of rocky particles, asteroids or satellites can be present. These elements gather around the planet at the time of its birth. Apart from this, due to events like asteroid impacts and meteorites, sand-rock debris is created around. If the planet exerts its gravitational influence on these elements, the elements either merge with the planet, or orbit the planet in a certain orbit. Sometimes become satellites. These do not occur unless the gravitational field of cosmic objects is strong enough. In that case the surrounding area remains impure.
As I said earlier, Pluto does well in the first two conditions. Pluto has enough mass to make itself spherical using gravity. revolves around the sun. But the third condition could not be fulfilled by Pluto even in hundreds of billions of years. Observations show that Pluto could not generate a strong enough gravitational field to clear the region around it. Besides, several other similar cosmic objects are found around Pluto. Together with these two, scientists decided to exclude Pluto from the list of planets. But since it fulfills the first two conditions, Pluto is included in the list of dwarf planets.
According to the Astronomical Union's definition, an object that orbits the Sun and has enough mass to form a sphere is called a dwarf planet. In that case, the object does not have to fulfill the condition of keeping its surroundings clean. No one has ever heard of such a case of losing a kingdom just because they couldn't jump.

However, Pluto is not alone even if it is left out of the list of planets. There are 5 other dwarf planets like Pluto in the solar system alone. Among them, Makimaki, Haumea, Eris, along with Pluto, are located outside the orbit of Neptune. Between Mars and Jupiter lies another dwarf planet, Ceres, in the asteroid belt.
However, despite losing its planethood, Pluto still has an additional benefit. Although the other ten dwarf planets of the solar system are not talked about, Pluto is being talked about a lot. A good example of a king who does not become lonely after losing his kingdom is Pluto, what do you say?
