What it means to be a Planet!

Since the 1960s, a few scientific articles have used the term "planet" and in orbits of other bodies in the solar system - at least in some large rotunda, including the moon - to help have an extra label "planet" if they want to talk more about all things around the sun. . You may have noticed that with extreme conservatism, I still refer to Pluto as something, not a planet.

If Pluto had been discovered ten years later when Edgeworth proposed the existence of the Kuiper Belt, it would not have reached the state of the planet. Pluto did a horrible job in 2006 when the IAU changed its definition of what it means to be a planet. Pluto was deposed when the International Astronomical Organization depopulated Pluto in 2006.

On August 24, 2006, our understanding of the solar system itself changed dramatically when researchers from the International Astronomical Union (IAU) voted to divide Pluto from planetary to sub-planet, a movement widely regarded as globalization and continues to be heard to this day. . . The public and many astronomers did not take this seriously and some said they would still regard Pluto as a planet. A heated debate ensued over many new proposals for defining the planet.

Finally, astronomers voted to agree with the controversial reorganization of Pluto (and Eris) as the new "small planet" as it had a strange orbit that exceeded Neptune's orbit and could not be said to have been removed Pluto's orbit around it. as a small planet, because it is not large enough to function in its orbital law and free up its surrounding space.

It was announced as the ninth planet from the Sun in 1930 after the discovery of Pluto. Since the 1990s, its planetary status has questioned the availability of a few objects of the same size on the Kuiper belt and disk. The IAU also classified it as a small planet and called it the "trans-Neptunian thing", which caused outrage among schoolchildren, fans of small planets, and the Internet in general.

Pluto was a revered planet for seventy-six years when it was abruptly removed in 2006 and from the family of nine elements of our solar system. For 76 years, he was known as the youngest and most distant member of the nine-member team, but the International Astronomical Union (IAU) changed everything. In 2005 the American astronomer Mike Brown thought that he had found a planet farther away from our solar system than Pluto.

On July 29, 2005, astronomers at the California Institute of Technology announced the discovery of a new Trans-Neptunian object called Eris that was much larger than Pluto and a massive object discovered by Triton in the 1846 solar system. in the world of astronomy, this process began a few decades after the discovery of smaller planets.

In 1992, scientists discovered the first Kuiper belt object, QB1 1992, a small body around Pluto, but in 2003 astronomer Mike Brown and others discovered a resident of Ring Road the size of Pluto.

As Eris grew older, made of the same mixture of ice and rock, and became larger than Pluto, the idea that we had nine planets in our solar system began to crumble. Scientists had to add many new planets to their list or remove Pluto rather than promote Pluto as one of the major categories of new things: these smaller planets. When Pluto was demoted, a wave of scientific literature was released to convince students of the millennium Pluto is a small planet.

In 2014, following a discussion among scientists sponsored by the Harvard-Smithsonian Center for Astrophysics, the majority of non-experts voted for a simple description of the planet - essentially a circle and orbiting a star or its fossils, including Pluto, according to the report. in an article on the institutional website for 2019. The 2006 argument that Kuiper Belt objects should be classified as non-planetary based on estimates of more than 200 years was "absurd"

According to the IAS, it is "c" that makes Pluto fail as a planet. Like other members of the Kuiper band, Pluto is considered a relic of planets; the first part of the protoplanetary disk orbiting the Sun that can fully assemble into a full planet.
