Planet x ?

Recommended Posts

Yeah, every so often I hear speculation of this.  Some theories could be substantiated if this is proven to be true.

 

But with an orbit that long it may still take many years before any evidence, if there is any, can be had.

 

Another wonder of the universe.

By studying data from Nasa’s Cassini spacecraft orbiting Saturn, the seventh planet from the Sun, French scientists confirmed that a ninth planet might exist in the far reaches of our solar system, co-author Jacques Laskar of the Paris Observatory told AFP, “but not just anywhere”. US astronomers announced in January that they may have found a ninth planet beyond Neptune but said it could take 10,000 to 20,000 years to orbit the Sun and they had no idea where it might be.

 

This past January, Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun at an average distance of 2.8 billion miles). In fact, it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the sun.

 

"This would be a real ninth planet," said Mike Brown, the Richard and Barbara Rosenberg Professor of Planetary Astronomy. "There have only been two true planets discovered since ancient times, and this would be a third. It's a pretty substantial chunk of our solar system that's still out there to be found, which is pretty exciting." The researchers, Konstantin Batygin and Brown, discovered the planet's existence through mathematical modeling and computer simulations but have not yet observed the object directly.
