*2 Too Far to See

Astronomer Clyde Tombaugh, who discovered
the planet Pluto in 1930, is convinced of
the existence of the mysterious tenth planet.

The Vulcanus enigma
-The possibility of a tenth planet is a tantalizing one. But what if the tenth planet is not on the edge of our solar system, but next to the sun? In the course of the past century, several astronomers have noticed the movement of a small point, similar to a planet, situated between Mercury and the sun. This hypothetical body has been named Vulcanus, but has never been definitely observed. The object may be a ring of dust or simply a passing asteroid.







If a mysterious celestial body exist, how do we explain the fact that the most powerful telescopes - for example, the Hubble Space Telescope - have not detected it? The answer is simple: if there is a tenth planet, we would have to look for it at the furthest reaches of our solar system, at least 4 thousand million kilometers beyond Pluto. This immense distance makes observation difficult. The only thing that is certain is that it is not a giant planet. If it were comparable to Uranus or Saturn,astronomers would have found it.
       Since research has produced no evidence, scientists are working on other hypothesis. Photographs made in the stellar observatory on the island of Hawaii between 1992 and 1994 indicate the existence of at least six primitive celestial bodies at a distance of several thousand million kilometers. If their existence is confirmed, these stars may prove that another planet could never be formed beyond Neptune and Pluto because there is too little matter at that distance and its concentration is too low. But for some astronomers, such as the Pluto discoverer, Clyde Tombaugh - there is reason enough to believe in the existence of the mysterious tenth planet.


***Nowadays, scientists are working hard on other hypothesis since this research had no evidence to prove the existence of the tenth planet. However, we exactly didn't know what was happening out there... Thanks for reading, guys!

*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.
