*1 Introduction

It follows a broad orbital paths, and then it disappears.
Some scientist believe that a tenth planet reappears at
regular intervals, accounting for the disturbances
in the orbit of Uranus.

In the infinite depths of space, all mater is in motion. As if moved by gears, the nine planets of our solar system orbit the sun, moving in their predictable elliptical paths. But something seems to be affecting the orbital path of Uranus, the seventh planet from the sun. Some astronomers are convinced that there could be another celestial body nearby. Is it possible that our solar system could have a tenth planet?





 


***Guys, I've read some articles and I'm going to post them here for everybody to enjoy. Maybe some of you had read this before, it's a theory of the existence of the tenth planet in our solar system. Enjoy!

There are nine planets in our solar system. Of these, there are the four earth-like planets whose surfaces are solid (Mercury, Venus, Earth and Mars); the four giant planets with fluid and gaseous surfaces (Jupiter, Saturn, Uranus and Neptune); and Pluto, the most distant planet from the sun. Out of the nine, there is no doubt that Uranus, the seventh planet from the sun, behaves in the strangest way. Uranus takes 84 years to orbit the sun; because of the 98 degrees tilt of its axis, 24 years of day alternate with 24 years of night, and the poles receive more heat than its equator. Uranus's orbital path is so irregular that it has been a rich source of information for astronomers for many years. Its striking deviations led to the discovery of Neptune in 1846 and Pluto in 1930.
         But the unusual orbital path of Uranus cannot simply be attributed to the influence of Neptune and Pluto, and about 2% of the planet's deviations cannot be explained. It seems as if Uranus is being attracted by an unknown celestial body of about the same mass as the planet itself - which is 14 times greater than the mass of the earth. In order words, there might be a tenth planet in addition to the nine known planets.
