This stuff fascinates me!
Planet Nine, potentially 10 times the size of Earth and orbiting far beyond Neptune in a highly eccentric orbit about the sun, was proposed in 2012 to explain perturbations in the orbits of dwarf planets just beyond Neptune's orbit, so-called detached Kuiper Belt objects. It has yet to be found, if it exists.
A similarly weird extrasolar planet was discovered far from the star HD 106906 in 2013, the only such wide-separation planet known. While much heavier than the predicted mass of Planet Nine -- perhaps 11 times the mass of Jupiter, or 3,500 times the mass of Earth -- it, too, was sitting in a very unexpected location, far above the dust plane of the planetary system and tilted at an angle of about 21 degrees.
The big question, until now, has been whether the planet, called HD 106906 b, is in an orbit perpetually bound to the binary star -- which is a mere 15 million years old compared to the 4.5 billion-year age of our sun -- or whether it's on its way out of the planetary system, never to return.
In a paper appearing Dec. 10 in the Astronomical Journal, astronomers finally answer that question. By precisely tracking the planet's position over 14 years, they determined that it is likely bound to the star in a 15,000-year, highly eccentric orbit, making it a distant cousin of Planet Nine.

Exoplanet discoveries have shown that super-earths, exoplanets having a size between that of earth and Neptune, are common. They’re usually rocky and are located in a star’s inner orbit like our sun’s Mercury, Venus, Earth and Mars.
There were probably 5 rocky planets in our solar system when it formed. There might even have been 6 had not Jupiter moved closer to the sun, stopping the formation of planet 6 or its merger with Mars and, most likely, causing the ejection of “Planet 9” to the far reaches of the solar system. The Asteroid Belt was the result of Jupiter’s interference in planet formation.
Another effect of Jupiter’s massive gravitation, and possibly aided by Saturn, was the flip flop in Uranus’ and Neptune’s orbits. Uranus used to be farthest from the sun.
The order of the 9 planets was probably once neatly sorted by size and distance from the sun, from the smallest to the largest:
Mercury,
Venus,
Earth,
Mars (the first super-earth if it had successfully merged with the Asteroid Belt),
“Planet 9” (the second super-earth if it had not been ejected),
Neptune,
Uranus,
Saturn, and,
Jupiter.
For whatever reason, Jupiter and Saturn moved closer to the sun, upsetting our neat and ordered solar system.

A planet spotted 336 light-years from Earth could help scientists learn more about whether there is a large "Planet Nine" or "Planet X" lurking in the outskirts of our solar system.
Why it matters: Scientists have been hunting for the hypothetical Planet Nine for years. The new characterization of this alien planet by the Hubble Space Telescope shows that worlds like the theoretical planet can exist in other solar systems.
Details: The exoplanet is "very widely separated from its host stars on an eccentric and highly misaligned orbit, just like the prediction for Planet Nine," Meiji Nguyen, an author of the new study about the planet in the Astronomical Journal said in a statement.

Hope the James Webb telescope really gets in space and working next year finally so we can find planet 9.

Regrettably, the JWST may not be of much help. It’s an infrared telescope, not optical. If Planet 9 is closer to the size of Neptune instead of earth it may be a cold gas ball. Also, at a predicted distance of 700+ astronomical units (similar to the planet in the article) it will be very difficult for any telescope to sight it.

space is a lie
astronomy is a fraudulent science designed to tickle nerdbois with bs like this instead of illuminating the obvious patterns, shapes and meanings of these lights in the firmament.

I bet you think NDT is like an actual intellectual with a gifted mind for science and not just a mid-wit agent pushing science onto other mid-wit nerdbois for the sole purpose of spreading disinformation and false perspectives.

Aww, wait you think the world is like real. That's cute.

Can we discuss your anger issues ?
