Pluto is first mentioned as Planet X by astronomer Percival Lowell. He reasoned that he was exhausted
because something caused small changes in the orbits of the planets Neptune and Uranus.
He considered only another body large enough to create a sufficiently strong gravitational field that could affect Neptune and Uranus. orbits.
Unfortunatley Percival Lowell died in 1916 without proving the existence of Planet X. In 1930,
astronomer Clyde Tomboyh discovered Planet X, 3.7 billion miles from our sun. He did it
using an astronomical telescope to expose a series of photographic plates. Plates are clearly shown
the small object moved against the background of distant stars.
This discovery was the result of a happy accident. Calculations which
the existence of a planet beyond the orbit of Neptune later provided an error. Voyager
2, it was possible to more accurately measure the mass of the planet Neptune. When this new data
variations of the orbits of Uranus and Neptune are used.
However, the new planet was named Pluto. Several names were suggested, including Zeus,
Cronus and Minerva. But in 1930, Pluto was officially marked by the ninth planet
The International Astronomical Union and is named after the Roman god of the underworld.
The axis of the poles of Pluto does not indicate "up" and "down" from the plane of the solar system
like planet earth. Instead, the point is closer to the sun. Pluto is usually further
from the sun than any other planet. But due to eccentric orbit, it is closer to
The sun than Neptune, for 20 years from a 249-year orbit. Pluto crossed the orbit of Neptune
January 21, 1979 and made its closest approach to the Sun on September 5, 1989. He stayed
within the orbit of Neptune until February 11, 1999. This will not be repeated until September 2226.
Pluto's odd orbit has led some to claim that it is a “trans-Neptunian violator”. That means it
more like a Kuiper comet than a planet.
The composition of Pluto is unknown, but its density (about 2 g / cm3) probably indicates that it is a mixture
and 30% water ice and 70% of rocks. Bright areas of the surface appear to be covered in ice.
nitrogen and less methane, ethane and carbon monoxide. Composition of darker areas
on the surface of Pluto is unknown.
Pluto has an atmosphere that probably consists mainly of nitrogen with some amount of carbon monoxide
and methane. It is extremely thin with a surface pressure of just a few microbars. The Pluto atmosphere probably exists as
gas, only when Pluto is near the Sun. For the rest of Pluto’s long orbit, atmospheric gases are frozen. Near
The sun may have some of the atmospheric gases go into space. NASA mission planners hope to arrive on Pluto
while the atmosphere is still in gas form.
In 1978, it was discovered that Pluto has a moon. Charon is officially named after the mythological
who ferried the dead across the river Acheron to the underworld. Charon was discovered
Jim Christie and may have been named after his wife Charlene. Before opening
Charon believed that Pluto was much larger because the images of the two were blurred together.
Pluto and Charon are unique in that they rotate synchronously with each other. This means that they
both support the same face to each other. It has been suggested that Charon was formed
a giant blow to Pluto, similar to the one that formed the Earth Moon. In 2005 a team using
The Hubble Space Telescope discovered two tiny moons revolving around Pluto and Charon.
They were called Knicks and Hydra. They are very small with a diameter of 40 to 60 kilometers.
Recently, there has been considerable controversy over the classification of Pluto. It has been classified as a.
the planet immediately after its discovery and remained so for 75 years. But in 2006, on August 24, the International
The Astronomical Union decided to change the definition of "planet." The new definition does not include Pluto.
Instead, Pluto is now classified as a “dwarf planet.” Personally, I do not agree to remove Pluto
status of the planet. I may be superstitious, but since any sailor worthy of his salt will tell you that
It is generally considered unsuccessful to change the name of the ship when it was baptized.
At the time of this writing, Pluto has not yet been investigated by a space probe. January 19, 2006
NASA has launched new horizons, which will be the first spacecraft to visit Pluto in July 2015. New Horizons

although much less. Any ring system poses a risk of damaging micrometeorites for new horizons.

I really hope that everything goes well, and the New Horizons space probe will send a huge amount of information about
“Planet X” or Pluto is known. Sometimes we will be able to settle debts about where
Pluto is really a planet or not.
