They dived to the bottom of hell, under the thick neon-methane atmosphere of Pluto. Flew in the snow storms of ammonia, every second fearing a break in the dark about huge needles durable as steel, water ice. They managed to find an area where there are mountains. The mystery of Pluto has been solved at last — this planet belongs to our Solar system. She captured her during the journey of the Sun through the Galaxy.

SEARCH OF THE WANDERERS
Amateur astronomer William Herschel, discoverer of Uranus
The discovery of Pluto, which for a long time officially considered the ninth planet of the Solar system, has its own history. Before the advent of telescopes humanity were well known five celestial bodies called planets (from the Greek for “Wanderers”, “wandering”): mercury, Venus, Mars, Jupiter, Saturn. During the four following centuries managed to open two more major planets, Uranus and Neptune. Continue reading
Oceans, of course, is extensive, and the mountains are impressive for its size. 7 billion people is also not a small number. Since we live on planet Earth (whose diameter is 12742 km), it is easy for us to forget how we, in fact, tiny. In order to realize it, all we need to do is look into the night sky. Looking at it, it becomes clear that we are just a speck of dust in an unimaginably vast universe. The list of objects below will help to see the greatness of man in the future.
The largest planet (by diameter 142.984 km)
Jupiter is the largest planet in the Solar system. Ancient astronomers named Jupiter king of the Roman gods. Jupiter is the 5th planet from the Sun. Its atmosphere consists of 84% hydrogen, 15% helium with small admixtures of acetylene, ammonia, ethane, methane, and water vapor hospita. The mass of Jupiter is 318 times the mass of Earth, and its diameter is larger than the earth 11 times. The mass of Jupiter is 70% of the mass of all other planets of our solar system. The volume of Jupiter can hold 1300 planets the size of Earth. Jupiter has 63 known satellites (moons), but almost all of them are very small and dim.

Scientists: the ninth planet in the Solar system — 500-ton piece of ice
The ninth planet has a mass of 10 Earth masses and is moving strongly forward on a bizarre elliptical orbit around a hot star. …The discoverers of the planet are unable to observe firsthand the ninth element of the Solar system, but scientists using mathematical and computer simulation calculated the trajectory of the most distant planet.
Scientists have shown video of the new ninth planet of our galaxy
Yet due to the insufficient capabilities of optics, it is impossible to see this mysterious object. Astronomers still argue that the chaotic motion of some space objects in the Kuiper belt indicates the presence of “the ninth planet”.
New planet: scientists have uncovered details
“Ninth planet” — so scientists call this mysterious object, which has so far failed to see due to lack of opportunities of modern optics, according to “BBC Ukraine”. Continue reading
