• Opening history
Pluto is the most distant planet from the Sun in its system. In addition, it is quite small and cold. The location of Pluto itself is forty times the distance to the Sun than the Earth. For quite a long time, Pluto was not seen or studied.
The theory that Pluto actually exists was put forward by an American-born astronomer in 1915. His name is Lovellpercival. It was only 15 years later that one of the Lovell Observatory workers, Tombo Clyde, proved the existence of Pluto. The discovery of the planet took place in the fact that a certain object was found in photographic images. He was like a star of the fifteenth magnitude. Clyde guessed that this was nothing but the ninth planet.
The name "Pluto" was given in honor of the god of the kingdom of the dead in the mythology of the ancient worlds.
It's not easy to spot this planet. You only need to look through a great telescope. Pluto is slowly rotating in its orbit. Because of this, the brightness is too weak and almost does not change throughout the year.
• Orbit
The approximate distance to the Sun is thirty-nine AU. Pluto also has one of the largest eccentricities in the Solar system, namely twenty-four hundredths. This means that the orbit will be the most elongated and longest. The point of rotation closest to the Sun in its orbit is 4447 million kilometers, and the most distant is 7392 million kilometers. Pluto was considered the eighth planet from 1979 to 1999. The reason for this is that its distance from the Sun was less to Pluto than to Neptune. Pluto orbits at a speed of 4.8 kilometers per second. It goes around the Sun in two hundred and forty-five years. The orbit is tilted to the ecliptic plane by seventeen degrees.
• Mass and radius
Pluto rotates around its axis in 153.29 hours, or about six days. The equator is tilted one hundred twenty-two and a half degrees relative to the orbit.
The mass of Pluto is six times less than the mass of the Moon. To be precise, its mass is approximately 1.5×1022 kg (this is a five hundredth part of the total mass of the Earth). Scientists calculated the mass of the dwarf planet not so long ago, immediately during the discovery of Pluto's moon, Charon, in 1987. The diameter of Pluto is approximately 2,490 kilometers. This is almost five times smaller than the diameter of the Earth and almost one and a half times smaller than the Lunar double radius. The planetary density is also low, at 1.7 grams per cubic centimeter. The speed of free fall reaches 0.78 meters per second squared.
There is an assumption that, perhaps, the planet is covered with ice.
• Atmosphere
Pluto has a very thin atmosphere. It consists only of methane, neon and argon. The pressure is too low compared to the Earth's pressure – on Earth it exceeds seven thousand times the Plutonic pressure. At the moment, snowfalls may soon fall on Pluto, they will consist of solid frozen methane. Pluto is now moving away from the Sun, and only in 200 years the atmospheric research will be repeated.
The standard temperature on Pluto is minus 123 degrees Celsius. In winter, it can drop to fifty Kelvin.
Thanks to the photographic images of the well-known Hubble telescope, astronomers have mapped the surface of Pluto. It is now known that the North Pole of the dwarf planet is covered with a snow and ice cap.
• "Denial" from the planet
The end of the twentieth century has become a source of doubt about whether the planet Pluto can be attributed to the greater planets, or not. Scientists have given good reasons:
All the planets that go beyond the asteroid belt are made up of gas, and they are giants, unlike Pluto, since Pluto is the smallest of all other known planets. Also, the orbital motion of this planet is too elongated and is crossed by Neptune. At this time, the International Astronomical Union has announced that the former status of Pluto as a planet will practically not be changed, only the word "dwarf" will be added, due to its size. Now the planet Pluto can be found in the catalogs of trans-Neptunian objects, where it has already been assigned a specific location number, this is for the coordination of various forms.
