Pluto Dwarf planet | Why was Pluto ejected from the solar system?
Introduction
In the General Assembly of International Astronomical Union 2,412 members gathered in the city of Prague in the Czech Republic to give a new definition to the civilized planet. Seven members of the Planet Definition Committee gave an explanation of the planet's interpretation. The vote was taken on August 24 after discussing it for a week, in which 424 members of the General Assembly voted.New defination of Planet
The Planet Definition Committee has interpreted to identify any celestial body as a planet :-Sun should be illuminated.
With its own gravity, its own liquids should be drawn towards the center and assumed a sphere.
The second planet should not be lunar and The path through which the revolution takes place in the spatial space of the orbit must have some difference in its gravitational effect.
And according to this fourth law, Pluto was not considered a planet. Because he did not influence gravity in his spatial space. Gravity is weak, so its effect is less than other planets.
According to the new interpretation of planets on the day of August 24, 2006, Pluto was removed from the planet and included in the lower position of the planet Vamana / dwarf. And the number of planets in solar-system(Suryamandal) decreased to eight.
Why was there a need to create a new definition?
The ancient Greeks called the planet celestial bodies. Mercury, Venus, Mars, Guru, Saturn, Sun and Moon got the status of planets. The Earth and the rest of the planets revolve around the Sun, according to Nicholas Copernicus 1543. After that those who revolve around the Sun were considered to be planets. Therefore, the name of the Sun and the Moon came out from the list of planets and the Earth was added, thus the number of planets was six.The matter settled here, but whether or not the orbiting comet was included in the list of planets? This question was not answered. In 1801, when the miniature called Siris was found, its diameter was only 930 kilometers. He was going to discover a planet. This was followed by the discovery of miniature eclipses like Palas (552 km), Vesta (521 km) and Heizia (450 km). But after this, due to the large number of minor eclipses being found, astronomy has removed all the minor eclipses from the planets and put them into a new group of miniatures.
Then the planet survived a total of six. Uranus feared in 1781, Neptune was found in 1846, and Pluto was discovered in 1930. Now the total number of planets is 9. There was no explanation of the planet, yet there was no difference of opinion among astronomers.
In 1992, David Zewitt and Jaime Lu of the US discovered new astronomical icy shells in the Kuiper Belt outside the solar system. More names were added to this list. Nevertheless, there was no need to explain the planets. But in 2005, American astronomer Mike Brown claimed Iris to be a planet one and a half times larger than Pluto. And released the tenth planet.
Now according to astronomy, the Kuiper belt was likely to have many other spheres, if all were counted as planets, the list would have been much longer. Were they a little older than Pluto, consider them planets? By the way, why even call Pluto a planet?
A seven-member Planet Definition Committee was formed for this problem. And then they settled the matter by giving new interpretation.
