It would be the fifth largest planet in the solar system. Remains to this date, no one has yet been observed. US researchers have found indications that a ninth planet, very big, exist in our solar system, they said Wednesday.
Where is it located?
The object, dubbed “Ninth planet,” would have a mass of about ten times that of Earth and would be in an orbit twenty times farther than Neptune, which evolves around the sun at an average distance of 4.5 billion kilometers.
In fact this planet would conduct a complete orbit around the sun between 10 000 and 20 000 years, the researchers point out, Konstantin Batygin and Mike Brown of the California Institute of Technology (Caltec) who made this discovery by means of mathematical models and computer simulations.
Are we sure of its existence?
If the existence of this object, which has not been directly observed, was confirmed, it would be “the ninth planet” in our solar system, noted Mike Brown, a professor of planetary astronomy. “There has been so far only two planets discovered in our solar system since ancient times and in this case it would be the third,” he has said. “There are still a large part of our solar system to be discovered and it’s very exciting,” added astronomer.
Pluto And then?
Pluto has long been considered the ninth planet of the solar system, but lost that status because it was too small. It is now classified as a dwarf planet. The new planet discovered will not have this problem: its mass would indeed be 5000 times that of Pluto.
