Scientists found that Sedna... had a weird orbit around the sun... hinted that another large mass in the outer solar system was gravitationally pulling on the miniworld...
Then, in a 2014 study, astronomers announced that they had detected... 2012 VP113, with an eccentric orbit similar to Sedna's... Since 2016, Brown, Batygin and others... have discovered even more eccentric TNOs — bringing the total to 13...
Planet Nine's composition is probably "most like Neptune," ... around 500 astronomical units away from the sun...
This far out, it could take between 5,000 and 10,000 years for Planet Nine to complete a single trip around the sun. Its orbit is probably highly elliptical... also likely does not orbit on the same plane as the rest of the planets...
Planet Nine's unusual orbit and extreme distance from the sun also raise the possibility that it could be a rogue planet... captured by the sun... However, Brown and Batygin believe Planet Nine likely formed alongside the other planets in the solar system...
Doubts about Planet Nine are rooted in alternative potential explanations ... an invisible giant disk of dust or a historic close encounter with a rogue planet... [or] that our model of gravity needs to be tweaked.
Others believe the apparent TNO kinks are simply an "observational bias," because it is easier to spot TNOs that are closer to Earth than more distant ones, Samantha Lawler, an astronomer at the University of Regina in Canada and a prominent critic of the Planet Nine hypothesis, told Live Science in an email...
In their most recent work, Brown and Batygin analyzed data from the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) at Haleakala Observatory in Hawaii and confidently ruled out around 78% of the suspected orbital pathway...

NASA’s most wanted: The 5 most dangerous asteroids to Earth

Planet Nine from Outer Space?
I’m more worried about the arrival of a new capture, and not too worried about that.
When would this Planet 9 have passed close to Earth? 10,00 years ago? 20,000? 50,000? Would any humans present at the time, if any, had maintained legends about it in some form?
Planet Nine is hiding behind Cloud Ten
Film at 11.
Or 12 O’Clock High.
And the clocks were striking Thirteen.
{cough}Pluto{cough}
Shades of Velikovsky.
...poor Rudolph, screwed again!
Behold, Pluto.
No! You mean the dreaded “Plan 9 From Outer Space!’’
Oh, not that!
Planet 9...Planet 9...Planet 9...
I never thought of our Solar System as being based on Mean Girls hierarchy, till now, that is.
“There goes the neighborhood!!!”
I hope there is no chance that Planet Nine’s orbit intersects with Earth’s
Planet Nine where are you...
More junk science.
