‘Ninth planet’ may exist in solar system: US scientists
MIAMI: A previously unknown giant planet may have been discovered lurking in the outer reaches of our solar system, US scientists announced on Wednesday.

Nicknamed Planet Nine, the object “has a mass about 10 times that of Earth” and follows a “bizarre, highly elongated orbit in the distant solar system,” said a statement by researchers at the California Institute of Technology (Caltech).

“In fact, it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the Sun.”

The report was published in the Astronomical Journal.
