By way of comparison, Neptune's orbit is about 30 AU from the sun.
...or a 100% chance that up to 40% of 'Planet Nine' exists (in one form or another), and a 50/50 chance the author 'gets lucky' this weekend...
;^)
There are probably many ‘rogue’ planets not attached to a particular star. Just wandering around the galaxy like any other debris leftover from novas and supernovas.
That’s the premise for the novel and movie “When Worlds Collide”..............That is one movie I’d like to see re-made with modern technology!................
I would think that, eventually, they would get pulled into a solar system at some point. Maybe I’m wrong. But if they did that’s definitely when “worlds collide”. Would kinda suck if a rogue planet tried to cut in line between earth and Venus.
That’s what happened in the book and movie.
The earth was ejected from the solar system nd the new planet took its place. A small cadre of scientists was able to make ‘The Leap’ to the new planet in a rocket ship and so were others from other countries................
“They can find exoplanets near stars light year away by virtue of dimming but they can’t find a planet on the edge of our solar system.”
Different problems. Exoplanets are, from our perspective, really close to the host star. So we know where to look. If planet 9 exists, it could be anywhere in a 360 degree circle from our perspective. And that’s assuming it orbits in the ecliptic. If it is a captured planet, it could be anywhere in the sphere around the earth.
The best data I have seen hints that we might have another planet by looking at dwarf planets that have weird orbits that might be explained by the gravitational influence of another planet way out there. That data doesn’t really point to where in the 360 degrees it might be.
This study is just a simulation based on theories about solar system formation. Kind of like the global warming simulations of earth’s future temperatures. Except the global warming models at least have some past data to model.
Hmm… how did it get land, drinkable water and a breathable atmosphere and all that?
Did they call the ship “Noah’s Ark”?
Light years away OH never mind.

AI told me “The Space Ark rocket in the 1951 film “When Worlds Collide” is named Pegasus.”
Yeah, “science”.

It came with one that had been frozen solid in deep space.
And it has been inhabited by a civilization before it was ejected from its own Sun. They knew they were going to be. There was even food left in storage facilities. Some was edible and the humans did. The sky was GREEN, but the humans didn’t know why until they awoke one morning to a green snowfall that was algae that produced Hydrogen and caused it to float. It was also edible........
They don't. Neptune's perihelion is still 900 million miles greater than Uranus's aphelion.
You might be thinking of Neptune and Pluto. From 1979 to 1999, Pluto was closer to the sun than was Neptune. Neptune's orbit is very close to circular, while Pluto's orbit is much more eccentric.
Yes after I posted I realized I meant Pluto. But figured someone would correct me 🤪
FR’s always good for that. :-)
40% of unknown, is still unknown.
But it’s known unknown.......................😁
