All the planets in our solar system orbit close to the sun's equatorial plane. Of the eight confirmed planets, the Earth's orbit is the most tilted, but even that tilt is still small, at just seven degrees.
It was natural, then, for astronomers to expect that planets orbiting other stars would behave the same way... But in recent years, new observations have revealed that the story is somewhat more complicated, at least for the oddest planets known, the Hot Jupiters.
...
Comparable in mass to Jupiter, they move on incredibly short period orbits, almost skimming the surfaces of their host star. Instead of Jupiter's sedate 12-year orbit, they whizz around with periods of days, or even hours. Finding planets on such extreme orbits meant a major rethink.
...
Then came another set of shocking discoveries. Rather than moving in the same plane as their host star's equator, some Hot Jupiters turned out to have highly tilted orbits. Some even move on retrograde orbits, in the opposite direction to their star's rotation.
...
The most widely accepted model of planet formation is "core accretion"...
But this simple model fails to explain the latest discoveries of planets on highly inclined orbits. The migration described above typically happens within the disk, keeping the planet close to the star's equatorial plane.
To excite it to a highly inclined orbit requires something more.
To date, astronomers have measured the orbital inclinations of 91 exoplanets and more than a third (36) move on orbits that are significantly misaligned, tilted by more than 20 degrees. Nine of them move on retrograde orbits.
Were there one or two misaligned planets, we could write them off as a fluke of nature. But the number found is far too large to be coincidence.

Unless it should be expected because of the Great Attractor synching orbits across the universe, it should not be unexpected that different solar systems or galaxies have a variance in orbits.
Clear proof of the fallout between the First Humans and the aliens from the (maybe) Zargon Galaxy.
What other explanation would/could possibly make any sense?
Wow, what a coincidence! Me and my buddies were discussing this very thing Friday night in the bar after our softball game.........Whoa........
[ The most widely accepted model of planet formation is “core accretion”... ]
What if most planet forms in interstellar gas clouds like stars and as stars move through them they capture them, and over billions of years the stars slowly “pull them into line” with their rotational planes?
K-pax is circling a binary star system and has a noticable wobble in it. Prot should have explained this already.
I can see how astronomers can detect the existence of an exoplanet via light obscuration. But to detect the rotational axis and rotational direction of the star? How in the world can they detect that?
God made laws pretty simple but pretty complex at the same time.
Since libs have no god except themselves then weird orbits must be caused by our cars. Clearly and obviously climate change because they are capable as God’s unto themselves to even affect other planets. Check, we may even be affecting the sun!
It should be pretty easy to explain, actually. Hot Jupiters are thought to have migrated closer to their star from much farther out, due to some gravitational interaction with something else. If this occurs suddenly, the planet will fall toward the star in a somewhat random trajectory.
It shows that our understanding of solar systems was child-like at best.
The abundance of systems like this is more a this time due to the fact that we only have looked at a tiny portion of stars, can only find planets that are big and in close/quick orbits, the easy of super-Jupiter making it easy to see them, and the fact that systems like ours would take decades to fully map out from here as our gas giants take 10 years and more to make a full orbit. Miss one transit, and that’s all you get.
I’m frustrated at the lack of Sol System analogs because it makes it less likely to find life-harboring planets, and it makes stable solar systems things that may be extremely rare, which is kind of disturbing.
Makes you count your blessings that this one is as “boring” as it is!
High mass planets orbiting close to stars are found most often because they are easiest to spot with our methods.
I really doubt that orbital inclination or retrograde orbits could reliably be determined.
What plane was your orbit in?
Anyone doing the retrograde?
Repeated observations. They probably measure the slight differentiation in the wobble to know what is happening.

This is how God messes with scientists' heads.
“But to detect the rotational axis and rotational direction of the star? How in the world can they detect that?”
Doppler shift and spot movements.
“He stretches out the north over empty space and hangs the earth on nothing.” — Job 26:7
Ah, Today, the Earth’s axis is tilted 23.5 degrees from the plane of its orbit around the sun. But this tilt changes. During a cycle that averages about 40,000 years, the tilt of the axis varies between 22.1 and 24.5 degrees. Because this tilt changes, the seasons as we know them can become exaggerated.
Those sorts of extreme planets are the only ones that can be easily identify at present. Makes sense since the wobble of the host star or dimming is the primary method of discovery. Nice, orderly little solar systems like ours must be much harder to identify.
You may thin k this is about marbles but it is the same process for planets.
