Pluto was discovered on February 18, 1930, by American astronomer Clyde Tombaugh at the Lowell Observatory in Flagstaff, Arizona. Initially hailed as the ninth planet in our solar system, Pluto's status was called into question in the early 21st century as astronomers debated its classification. In 2006, the International Astronomical Union redefined the criteria for what constitutes a planet, leading to Pluto's reclassification as a dwarf planet.
Pluto is located in the Kuiper Belt, a region of the solar system beyond the orbit of Neptune that is home to a vast array of icy bodies and dwarf planets. Due to its distant location and small size, Pluto remained largely unexplored until recent decades. In 2015, NASA's New Horizons spacecraft made a historic flyby of Pluto, providing the first up-close images and scientific data about this distant world.
Characteristics of Pluto
Pluto is a small and icy world with a diameter of approximately 1,473 miles, making it smaller than Earth's moon. Its surface is composed of a mixture of rock and ice, with large regions of frozen nitrogen and methane. Pluto has a thin atmosphere primarily made up of nitrogen, along with traces of methane and carbon monoxide.
The question of whether Pluto really exists may seem trivial, but it has sparked intense debate among astronomers and scientists. While Pluto's existence is not in doubt, its classification as a planet has been a topic of discussion for decades. In 2006, the International Astronomical Union (IAU) redefined the term "planet," which led to Pluto's reclassification as a dwarf planet .
So, why is Pluto not considered a planet? The IAU's definition of a planet requires it to "clear the neighborhood around its orbit," meaning it must be the dominant object in its orbit .Pluto, however, is part of the Kuiper Belt, a region of icy bodies beyond Neptune's orbit, and has not cleared the neighborhood around its orbit.This criterion is what distinguishes planets from dwarf planets.
Despite the controversy surrounding its classification, Pluto's existence is well-documented. Its discovery in 1930 by Clyde Tombaugh marked a significant milestone in astronomy .Pluto's existence is determined through a combination of observations, including its orbital pattern and the effects it has on its surroundings. Astronomers have also sent spacecraft, such as New Horizons, to study Pluto up close, providing valuable insights into its composition and structure .
So, what does Pluto look like? Pluto is a complex and mysterious world, with a surface featuring mountains, valleys, plains, craters, and glaciers . It is the largest known dwarf planet in our solar system, with a diameter of approximately 2,374 kilometers .Pluto's surface is characterized by a diverse range of geological features, including the Norgay Montes mountain range and the Sputnik Planum ice plain .
In conclusion, while Pluto's classification as a planet may be disputed, its existence is undeniable. Through a combination of observations and spacecraft missions, scientists have gained a deeper understanding of this enigmatic world. Pluto's unique features and composition make it a fascinating subject of study, and its reclassification as a dwarf planet has not diminished its importance in the field of astronomy.
The Legacy of Pluto
Despite its reclassification as a dwarf planet, Pluto continues to captivate the imagination of people around the world. Its unique characteristics and mysterious features make it a fascinating object of study for astronomers and space enthusiasts alike. The exploration of Pluto by the New Horizons spacecraft has opened up new avenues of research and discovery, shedding light on the complex and dynamic nature of this distant world.
As we continue to unravel the mysteries of Pluto and the outer reaches of our solar system, one thing is clear: this tiny dwarf planet

3. 5 unsolved secrets of the world
The case of lead masks - this is the story of two corpses found on Winn Hill near the city of Niteroi in Brazil on August 20, 1966. The name of the case was given to two lead masks found on the faces of the dead. Both corpses were lying on a bed of leaves, dressed in business suits and waterproof raincoats. Next to the bodies lay a notebook in which there was a note with approximately the following content: "16:30 be in a designated place 18:30 swallow the capsule and after which illegible words and the word mask." The dead were local radio engineering is interested in ufology. So one of the police versions was that they were killed by lightning or that they were experimented on and all their money was stolen. However, the first version was rejected by experts and the second version seemed too far-fetched. There were also versions that they were plunged into a trance or something else, a UFO is to blame for their death. However, the death of these people is still shrouded in darkness. Mysteries, see electrical shop number 10, all sorts of legends. Of course, everyone refers to a gas leak, some kind of explosion, an accident, but not. The story of the orange Medan ship begins in 1947 when two American ships received an SOS signal for help. A man who was a member of the crew of a Dutch ship, an orange Medan, a man screamed, everyone is dead and soon it will come for me, then after a strange noise, the sailor said I’m dead and the broadcast stopped. Having come to the aid of the ship in distress, American ships discovered the corpses of all crew members. And despite the fact that they died many hours ago, their body temperature was over 40°. When they tried to tow the ship, it caught fire and exploded, sinking to the bottom. And despite the story of both crews of American ships, many claim that the ship named Orange Medan simply did not, there was, however, there is evidence from several people that their relatives were hired on such a ship and there are even two photographs of this ship, however, neither the purpose of the voyage nor the cause of the disaster is known, how did the crew die. October 21, 1978, excellent flying weather plane from Rabin with a pilot named Frederic Valenti who has more than 50 hours of flying practice behind him. In the middle of the flight, the pilot contacts the base and asks if there are military aircraft flying near him, receiving a negative answer he began to talk about the fact that that big plane is flying over it as if it was starting some kind of game for 6 minutes while there is a dialogue between the pilot and the dispatcher, the connection is constantly lost and the pilot coughs more and more, and then in 1912 the connection with the pilot stops, the search teams sent to search for the plane, nothing they didn’t find anything other than an oil stain on the bass strait, and that stain was not the plane’s fuel; an interesting fact was the pilot’s last words that it was not an airplane. However, knowing about his passion for ufology, one can assume that this is all mind games, however, Australian ufologists consider this one of the most reliable evidence of contact of aliens with us is still not clear what happened to Valentich. However, among cynics, thoughts of suicide and faking death prevail Although the plane and pilot were never found. Canadian Oak Island hides many secrets, one of them - this is the possible discovery of untold riches in the so-called money mine. The history of the discovery of this mine is somewhat different: someone says that children aged about 16 years old stumbled upon it in 1975, someone says that an old sailor who drowned in 1805 spoke about the mine and treasures when his grandson found a map of the island from my grandfather and took it to my grandfather’s colleagues, who without hesitation promised to help. However, it burned down along with all the documents. The very next night, under the ashes, a deep mine was discovered, which many generations of treasure hunters began to dig up; they went deeper into the mine. However, despite the fact that 60 m had been dug, it was not possible to find the treasure, whether there were treasures there and whose they actually are still remains a mystery. However, interest in the money mine is fading away every day and brought only a few stories on a similar topic. Yes, a documentary series about the excavations of the mine on Oak Island. One of the most famous serial killers acted in London in the second half of 1888, the Whitechapel killer, aka Jack the Ripper, is one of the most famous names of a serial maniac. In addition, the maniac has many uncaught victims. However, the number ranges from 1 to 15, although only five victims of the Ripper are considered canonical; they were prostitutes whose throats he strangled and cut; an interesting feature of the criminal was that he was sure that he would not be caught; this is evidenced by the letters he wrote to the police; there were many letters received. However, only three were definitely sent by Jack the Ripper, by the way, the name appeared from the first letter; the most notable ones are considered the third letter, called from hell, delivered with half a kidney; the letter says that the second half was eaten by a maniac; there were many suspects in the case; however, it was known for sure about the surgical skills of the maniac; nevertheless, Jack also disappeared suddenly, how he appeared and it is still unknown who he was and why he disappeared. Did he die, did he go to prison, did he escape from London, all these theories apparently will remain theories without shedding any light on this mysterious killer.
