New evidence points to giant 9th planet on solar system edge…is the Planet X?

This one is 5,000 times bigger than outcast Pluto and billions of miles farther away, say scientists who presented “good evidence” for a long-hypothesized Planet X on Wednesday.

The gas giant is thought to be almost as big as its nearest planetary neighbor Neptune, quite possibly with rings and moons. It's so distant that it would take a mind-blowing 10,000 to 20,000 years to circle the sun.

Planet 9, as the pair of California Institute of Technology researchers calls it, hasn't been spotted yet. They base their prediction on mathematical and computer modeling, and anticipate its discovery via telescope within five years or less.

The two reported their research Wednesday in the Astronomical Journal because they want people to help them look for it.

“We could have stayed quiet and quietly spent the next five years searching the skies ourselves and hoping to find it. But I would rather somebody find it sooner, than me find it later,” astronomer Mike Brown told The Associated Press.
