The Story of Banished Planet Part-1
A Planet removed from our Solar system named pluto.
Pluto is not a planet anymore.
IAU ( International Astronomical Union) declared that there are only EIGHT (8) planets in our solar system not NINE (9).
Some of the phrases like this were spread around the world on 25th August in 2006.
Note this date because a sensational decision had taken in this date in Astronomical world by IAU.
In place IAU, PRAGUE, CZECH REPUBLIC (Europe) there a meeting that held Astronomical unit in 25th August 2006.
The total members in IAU now :- 12,131 individual members
President of IAU :- Debra Meloy Elmegreen
But the total members of IAU in 2006 is approximately 10,000 but in 10,000 members atleast 10% members did not participated in that meeting.
That 10% scientists in IAU declared that pluto is removed as a planet and considered as a dwarf planet.
But some scientists are still opposes this decision.
Note :-
This Article is divided in two parts because i want to explain total things of Pluto. About Why Pluto is removed as planet?. What is the Condition in Pluto. What is the atmosphere of Pluto.
In this Article I'll explain why Pluto is removed as a planet and considered as a Dwarf planet
And I'll explain the atmosphere, Time period and other things of Pluto in Part -2.
Pluto is discovered by Clyd Tombaugh in 18th Feb 1930.
And it was removed as a planet in 26th August 2006.
These are the pictures of our solar system before 25th August 2006 and After 25th August 2006.

Why Pluto is Removed as planet and considered as a Dwarf planet?.
At that time there was a rule that a planet had to pass three tests to be a planet.
Test-1 :- For any planet to be considered as planet, it has to revolve around the sun.
However Pluto is passed in that test.
Test-2 :- A celestial body must have the mass to be able to shape itself into a spherical shape.
Pluto is passed in this test also.
But Pluto is failed in the third test. That's what it is..
Test-3 :- It should be able to clear it's plath.
Clearing it path means? It has to clean?
Of course Not.
Clearing means. If any Asteroid or Metroids or any dwarf things comes in a way of the Celestial body when it is revolving around the sun. It has to attract that things with gravity (or) It has to make the asteroids that come in the way orbit around it.
Pluto is failed in this test. But in my way it's not the proper reason to remove the Pluto as a planet . Because Pluto rotates Five Spacial objects around it with it's range of gravity They are called as Pluto's Moons.
Pluto is very far from sun. So Pluto is a COLD & DARK planet it's Orbit is very clear already.
Some scientists says that Pluto comes to Neptune's Orbit. So Pluto does not deserve to be a planet.
In my opinion it is right because Pluto is very far from sun. So it's Orbit is very Dark and Cold And Pluto takes 248 Earth years to make one revolution around the sun.
In that 248 years, 20 years Pluto come near to the sun. How close it is...
In that 20 years, The distance between Sun and Pluto is less than the distance between Sun and Neptune.
Because of this reason some scientists says that Pluto is not Considered as a planet.
Because it crosses another planet's Orbit.
Some scientists still opposes this decision also.
Tell us what you think about this decision in the comments.
Thank you for reading❤.
