'Planet Nine' Could Be an Alien Intruder
New dynamical simulations suggest that the mysterious unseen world might be an interstellar rogue that was captured by our solar system.
| There are few solar system mysteries quite as compelling as "Planet Nine." The hypothetical world, thought to be orbiting at an extreme distance | By Ian O'Neill seeker.com 1-13-17 |
Calculated to scoot as far away as 1,000 AU from the sun (when 1 AU, or astronomical unit, is the average distance at which the Earth orbits the sun), there's a huge question mark hanging over how it even formed - it had to have evolved far closer to the sun and then some gravitational process migrated it away. This extreme orbit has led to other ideas that Planet Nine might have been pilfered by our sun when it passed close to another star system in the past.
But there's an alternative hypotheses that suggests Planet Nine is actually an alien intruder; a captured "rogue" or orphaned planet that was adopted by the solar system.

'Unknown Objects' Could Be Planet Nine
 |
| Astronomers have been hunting for Planet Nine — the large, mysterious body thought to lurk at the edge of our solar system — ever since researchers at Caltech published evidence of its existence last year. | By Sarah Kaplan The Washington Post 4-4-17 |
Ordinary people have now joined the search. And they've made some intriguing finds.
Participants in a citizen science campaign hosted by the crowdsourcing program Zooniverse, and the BBC pinpointed four previously unknown objects in the outer solar system that could be candidates for Planet Nine, according to researchers at the Australian National University.

Mysterious ‘Planet Nine’ Causing The Solar System To Wobble?
 |
| “Because Planet Nine is so massive and has an orbit tilted compared to the other planets, the solar system has no choice but to slowly twist out of alignment...” |
| Astronomers can't see “Planet Nine.” But it makes its presence known. The massive hypothetical object, which supposedly looms at the edge of our solar system, has been invoked to explain the strange | By Sarah Kaplan The Washington Post 10-20-16 |
Now Planet Nine predictors Konstantin Batygin and Mike Brown of Caltech, along with graduate student Elizabeth Bailey, offer another piece of evidence for the elusive sphere's existence: It adds “wobble” to the solar system, they say, tilting it in relation to the sun.
“Because Planet Nine is so massive and has an orbit tilted compared to the other planets, the solar system has no choice but to slowly twist out of alignment,” lead author Bailey said in a statement.

Mysterious 'Planet Nine' Tilted Our Solar System?
| Two recent studies have shown that the existence of a mysterious, hypothetical Planet Nine could explain why the planets in our Solar System don't fully line up with the Sun. | JOSH HRALA www.sciencealert.com 7-20-16 |
In fact, if Planet Nine does exist (or did), it would help to explain something that scientists have puzzled over for decades - why the Solar System is tilted.
What does that mean? ...

Is Mysterious 'Planet Nine' Tugging on NASA Probe?
| Astronomers are homing in on the whereabouts of a hidden giant planet in our solar system, and could discover the unseen beast in roughly a year | By Shannon Hall ScientificAmerican 4-5-16 |
The hunt is on to find “Planet Nine”—a large undiscovered world, perhaps 10 times as massive as Earth and four times its size—that scientists think could be lurking in the outer solar system. After Konstantin Batygin and Mike Brown, two planetary scientists from the California Institute of Technology, presented evidence for its existence this January, other teams have searched for further proof by analyzing archived images and proposing new observations to find it with the world’s largest telescopes.
Just this month, evidence from the Cassini spacecraft orbiting Saturn helped close in on the missing planet. Many experts suspect that within as little as a year someone will spot the unseen world, which would be a monumental discovery that changes the way we view our solar system and our place in the cosmos. “Evidence is mounting that something unusual is out there [...]
