Dwarf planet Pluto

• History of discovery
Pluto is the planet most remote from the Sun in its system. In addition, it is rather small and cold. The very location of Pluto is forty times the distance to the Sun than the Earth. For a long time Pluto was not seen and not studied.
The theory that Pluto is actually there, put forward an astronomer, a native of America, in 1915. His name is LovellPersival. Only 15 years later, Pluto proved the existence of one of the workers of the Lovell Observatory in the name of Tombo Clyde. Detection of the planet took place in the fact that there was an object in the photographs. He was like a star of the fifteenth magnitude. Clyde guessed that this is nothing but a ninth planet.
Name & quot; Pluto & quot; was given in honor of the god of the kingdom of the dead mythology of the ancient worlds.

It is not easy to see this planet. It is necessary to look only in an excellent telescope. Pluto slowly orbits. Because of this, the brightness is too weak and almost unchanged throughout the year.
• Orbit
The approximate distance to the Sun is thirty-nine au Also, Pluto 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 closest point to the Sun's orbit is 4447 million kilometers, and the outermost point is 7392 million kilometers. Pluto was considered the eighth planet of 1979 to 1999. The reason for this is that the distance from the Sun was less to Pluto than to Neptune. Pluto in orbit moves at a speed of 4.8 kilometers per second. It passes around the Sun in two hundred and forty-five years. The orbit is inclined to the ecliptic plane by seventeen degrees.
• Weight and radius
Pluto makes a circle of rotation around its axis in 153.29 hours or approximately six days. The equator is tilted one hundred twenty two and a half degrees in relation to the orbit.

The mass of Pluto is six times smaller than the masses of the Moon. To be precise, its mass is about 1.5 × 1022 kg (this is the 500th part of the total mass of the Earth). The scientists of the dwarf planet were considered not so long ago, just at the time of the discovery of the satellite of Pluto, called Charon, in 1987. The diameter of Pluto is approximately 2490 kilometers. It is almost five times smaller than the diameter of the Earth and almost one and half times smaller than the Lunar Double Radius. Planetary density is also low - 1.7 grams per centimeter in a cube. The speed of free fall reaches 0.78 meters per second in a square.

There is an assumption that, perhaps, the planet is covered with ice.
• Atmosphere
Pluto has a highly rarefied atmosphere. It consists only of methane, neon and argon. Pressure, compared with Earth pressure, is too low - on Earth it exceeds seven thousand times the pressure of Plutonium. At the moment, snowfalls on Pluto can soon go, they will consist of a solid frozen methane. Pluto is now moving away from the Sun, and only 200 years later, the study of the atmosphere will be repeated.

The standard temperature on Pluto is minus 123 degrees Celsius. In winter, it can fall to fifty in Kelvin.

Thanks to photographic images of the well-known Hubble telescope, astronomers compiled maps of the surface of Pluto. Now it is known that the North Pole of the dwarf planet is covered with a snow and ice cap.
• "Negation" from the planet
The end of the twentieth century was a source of doubt as to whether Pluto could be referred to the larger planets, or not. Scientists have given good reasons:

All the planets that follow the asteroid belt are gas, and they are giants, unlike Pluto, since Pluto is the smallest of all the other known planets. Also, the orbital motion of this planet is too elongated and intersected by Neptune. At this time, the International Astronomical Union announced that the former status of Pluto as a planet will not be changed, only the word "dwarfish" will be added, thanks to its size. Now the planet Pluto can be found in the catalogs of the trans-Neptunian objects, where it has already been assigned a certain number of locations, this is for approvals of various forms.
