Demotion of Pluto: Dwarf Planet

Since Clyde W. Tombow first discovered Pluto in 1930, it was seen as a strange planet that brought its reclassification in 2006. For decades Pluto has been used as the criterion for the extent and size of the solar system. In recent years, a new discovery of celestial bodies near Pluto's orbit has challenged the state of that planet. Discussion on the classification of Pluto in several media and news articles has brought about a serious controversy among astronomers and a decision on whether Pluto should be classified as one of the planets of the solar system.

However, 76 years later, astronomers seemed to downgrade Pluto to dwarf state and place it next to the Kuiper belt and the other large and small planet Ceres, reducing planet number of the planet to only 8. Last year, a team of scientists proposed a new definition of a planet that regained Pluto, this definition is the mission of a new vision and was acknowledged by Alan Stern and David Greenspon, the author of the new book Earth. . "Pluto In 2006, the International Astronomical Union did what has never been done, and scientifically defined one of the oldest terms of astronomy - a planet - I know it "Although this definition has been attacked for various reasons, such as Kuiper Belt and an increase in Cross Neptune objects discovered elsewhere, many of them are circular and have enough gravity to remain in hydrostatic equilibrium I'm waiting.

If we do not really pay attention to our solar system Pluto, we all grow up and we are learning the planet, especially the ninth planet. Planets "Two other dwarfs with the same size and similar orbits as Pluto are the planets. The astronomers of Chad Trujillo and Scott Shepard first became Planet 9 in 2014 (when going to see a documentary also known as "Planet Nine"). The unique trajectory of a small object is the cause of the belt over Neptune 's orbit.
