Pluto: The Downgraded Planet

Introduction Although NASA and the International Astronomical Union explain this, Pluto will always be regarded as my planet. When I was a child, I was always fascinated by Pluto; because it was the smallest of the nine planets. The main reason is that it is the smallest planet in our solar system and the last of the nine planets was discovered. In 2006, when I learned that Pluto was downgraded to a smaller planet by the International Astronomical Union (IAU), I did not satisfy the newly established standard anymore and classified it as a planet Was disappointed.

The Illinois State Senate passed a resolution to return Pluto to the state of the earth on February 26. Congress voted to "unjustly demoted" the planet of the dwarf through Pluto in 2006. According to other countries in the world, Pluto is still a dwarf. Pluto was discovered by the 19-year-old Streiter astronomer in Illinois. The planet is celebrated on Pluto's Day, and Dr. Clyde Tobo, March 13

Pluto has been downgraded from the planet to what is now considered a dwarf. By redefining the planet and dwarf, a new planet has been identified. These dwarfs are through the Neptune on the Kuiper belt. This is the information that led the researcher to believe that there is the ninth planet. The California Institute of Technology believes that Planet 9 exists, but it is also ten times the mass of the Earth. Planet Nine is far beyond the standard boundary of the solar system, and it takes 20,000 earth years to fully orbit the sun.

A few months after the launch of the new horizon, the astronomers of the International Astronomical Union voted to change the definition of the word "planet". But yesterday, NASA 's chief executive Charles Bowden said he hoped to rethink the official classification, overcoming the resurrection controversy. "I call it a planet, but I am not a ruler," he said. Alan Stern, New Horizon 's mission commander, closed the hatch of the spaceship and was the person who finally bid farewell when it was launched nearly 10 years ago. But his cheerleading team for the scientific exploration of Pluto can be traced back to the previous decade where Pluto's mission is floating on NASA and then be discarded or shelved I will. "If Pluto's mission is a cat, it died long ago because it has more than 9 lives," he said.

Currently, the definition of the planet that the International Astronomical Union Association (IAU) used to lower Pluto's position has not been applied has been discussed in recent decades. And in the past 2 centuries. Philip Metzger, the first author of this paper, a planetary scientist at the University of Central Florida and published online on Ikars magazine on September 5, says: "In recently published literature, it is said that it is not a planet in the definition of IAU, but it is called a planet, but there were 120 examples of scientists who violated the definition of IAU."
