In the year 1840, as usual, the French scientist Urban Louvre, who was busy with his work, noticed something. Uranus deviates from its orbit by miscalculation. He did not understand the reason for this. .
September On September 23, 1846, Johann Galle calculated the position of the eighth planet based on the calculations of Urban Lev Varier with the help of Mathmatics … and the planet was in the same position as he had predicted. … The most important thing is that we discovered Neptune with the help of Mathmatics.
But the problem does not end there. Subsequent research revealed one thing to them. Neptune is not the only Uranus orbital variant .Scientists were trying to find the ninth planet.
Percival Lowell established the Lowell Observatory in Arizona in 1906, marking the beginning of a mission to find the ninth planet. He named the mission “Planet X”. In 1909 Lowell and William H. Pickering suggested some possible locations for the planet. Lowell continued his search until his death in 1916, but he was not fortunate enough to find Pluto.
In fact, the photographs he actually took on March 19, 1915, and April 7, 1915, contained very dim images of Pluto. But he could not recognize this
In 1929, the mission landed on a young scientist named Clyde Tombag. Tombag’s study was based on images of the night sky. He studied the motions and brightness variations of celestial objects in these photographs. It was later authenticated by analyzing more images. On March 13, 1930, he discovered that it was a planet and telegraphed the discovery to the Harvard College Observatory.
But the problem does not end there. Discovered Pluto had a mass of 0.2% of the Earth. This mass can never change the path of Uranus. Scientists are trying to find a giant planet that could change the orbit of Uranus.
In 1992, the planetary status of Pluto was widely discussed. Many Pluto-like objects were found in the Kuiper Belt. Thus the number of planets began to increase. The problem was that there was no exact criterion for what a planet is. Then the criteria for an object to become a planet were released by the International Astronomical Union.
1.The object must rotate a star
2.The object must have achieved a spherical shape due to its own mass.
3.In the term of rotation of an object, objects with a mass greater than its mass should not be present.
Pluto lost its planetary status due to a third criterion. This is because Pluto is crossing the orbit of Neptune. Therefore, Pluto lost its planetary position due to the arrival of a neptune with a mass called Carl Mass in its orbit.
In dwarf mythology, the dwarf planet was named after Pluto, the god of the underworld. It is noteworthy that Pluto has not orbited the Sun even once since its discovery. It will be completed in 2170.
After Neptune, objects are known as Trans Neptune Object or TNO. Pluto is the most famous TNO
When Astronomers Batak and Brown observed some TNOs, they realized something. Some of them are located on the same side. There was no definite explanation for this. Their hypothesis is that there is a ninth planet in the Solar System and that these TNOs are located on the same side because of its gravity.
The location of Planet Nine will be 400 to 800 astronomical units. That would be 13 to 23 times the distance between the Sun and Neptune. Planet Nine orbits the Sun once every 10,000 to 20,000 years. The planet, which is five to ten times the mass of Earth, is now in the form of a mathematician
