Why was Pluto fired?
2006, the solar system was described to you like this: Mercury, Venus, Earth, Jupiter, Saturn, Uranus, Neptune, Pluto. These were in that order.
. But if after the year Go to school in 2006, you will see that Pluto has been removed from the category of a planet, it has not gone anywhere, it is going around the sun as always in its usual orbit. Our topic is why it was removed? Pluto has not changed at all, with its predecessor. It doesn't hurt, but human science has progressed a lot and we understand that Pluto is not a planet. Pluto was discovered in 1930, it's not even a hundred years old. In order to understand whether Pluto is a planet or not, we need to understand the meaning of being a planet. The meaning of being a planet has changed many times. At the time of Galileo, they believed that "everything that revolves around a star is a planet." Everything went well until 1801.In this year, Ceres was discovered, it was a dwarf planet (asteroid), which revolved around the sun between Mars and Jupiter, it was then that they realized that Ceres was very small and the size of a third of the moon. The next year (1802 AD) another dwarf was discovered, named Pallas. Then more were discovered, until they realized that there are thousands of them.@And you can't call these planets, why?@Because they were very different from other planets and they were much smaller and most importantly they were not perfectly spherical, they named them asteroids. It was until Pluto was discovered.@So why didn't they consider Pluto as an asteroid in the first place? Because they didn't know how this planet behaves, so they correctly failed the planet test, they couldn't figure out its size at the beginning of the discovery. So they couldn't say the size, but it wasn't bigger than this mistake.You should know that Pluto is very distant from Earth and the last thing in the solar system. Time passed, technology improved and the device became more advanced, understanding that Pluto is smaller. Finally, in 2006, it got its exact size. Bringing and understanding that Pluto is very small and an asteroid, if you want to put Pluto in the earth, 459 Plutos will fit in the earth, the size of the moon, the size of half the moon. In 1978, scientists also found the moon of Pluto.When you say that this is a planet, it even has a moon, but the size of the moon was half the size of the planet itself! This big moon causes Pluto itself to rotate in a circle in addition to rotating around itself@It means that the moon is so big that it moves around, and this is the point that it loses its planet status, that is, a planet that does not have the force of its moon does not deserve to be a planet, but scientists wanted to be friends until Iris in 2005. Eris) was discovered @@Iris is something like Pluto but much smaller, it is placed after Pluto. @@And it revolves around the sun, and since it was not a planet, Pluto is not a planet and is an asteroid.@From then on, they set rules for being a planet@1- A planet must revolve around the star.Well, Pluto revolves around the sun@2- It must be spherical, well Pluto was like this@3- But in the third law, Pluto is deprived of it, the planet must be equal to its own area, that is@He and his moon are alone in space, if Pluto is full of occupation around him.But everyone disagreed and said that it has 2 laws, but the scientists replied: "If it was like this, all the asteroids should have been added, our own moon, 79 to the moon of Jupiter, and worse than that 84 moons of Saturn, so if like this You can count if you want, the 8 planets of the solar system will turn into hundreds, first you should know that the distance between Pluto and the sun is 5,900,000,000 km and this has caused its temperature to be 232 degrees Celsius below zero. It has not been done, but it is understood that this asteroid is made of rock and ice, a day and night of this planet lasts 6.5 Earth days, and a year is 248 Earth years, but many people disagree and say that this planet is, they may say that this planet is in 50 years. LT is.@In short, thank you very much, God bless you
