Is this really news?
Don't we hear the same statment made every 5 or 6 years.
I mean they have been looking for a planet X since the 60's based on math.
The idea that maybe its several smaller objects was in the 80s...
This sounds like just a rehash of that same ole same ole
Quoting: vind21 It has been substantiated to be more than mere calculations ... They've been aggressively searching for planet x's for a decade now - someone give Phil Plait a call - Planet x's are real !!! "This past March, astronomers Scott Sheppard of the Carnegie Institution for Science and Craig Trujillo of Gemini Observatory in Hilo, Hawaii, saw a new object, the most distant known in the solar system. This object, about 200 miles in size, and several near it followed similar orbits, an unusual occurrence, according to Sheppard."
“We would expect their orbits to be fairly random,” he told weather.com. “So we suspect something more massive is shepherding these.” A planet, to be exact. They called it 2012 VP113 or VP for short, after Vice President Joe Biden, and reported their findings in the journal Nature."
"Since then, several other scientists have tried to find explanations to the orbit question. Reporting in the Monthly Notices of the Royal Astronomical Society Letters in June, two researchers at Madrid’s Complutense University concluded based on their analysis that two planets “must exist” beyond Neptune and Pluto. Another reported in the same journal in August that these planets are likely even more distant than imagined.""Sheppard said other questions remain about these planets, not just whether they exist. “How did this large object get out there and where did it actually form? Did it form in our solar system or did it actually get captured from another solar system?” He noted that because objects like that cannot form in the outer solar system, they must have been “tossed out there” with help from large planets like Jupiter, Saturn, Uranus or Neptune."
