Though astronomers are still searching for a hypothetical “Planet Nine” in the distant reaches of our solar system, an exoplanet 336 light years from Earth is looking more and more like the Planet Nine of its star system.
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.
Astronomers have yet to find it, 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.

Hubble Finds Exoplanet That Could Mirror Planet Nine By Ryan Whitwam on December 14, 2020 at 8:16 am

The Hubble Space Telescope has been spying on a very unusual exoplanet some 336 light years away. The planet, known as HD 106906 b, is 11 times the mass of Jupiter, and it orbits the binary stars at a distance of nearly 68 billion miles 730 times greater than the distance between Earth and the sun. Astronomers believe this frigid world could serve as a proxy to help us understand the hypothetical Planet Nine in our own solar system.
Explained: In weird planet 336 light-years away, clues about our own Planet Nine
Like the presumed Planet Nine in our Solar System, newly described exoplanet orbits its star from a great distance, at an extreme tilt, and influences the behaviour of various objects in its system. What have scientists learnt about its formation and behaviour, and how does it mirror Planet Nine?

A strange exoplanet, orbiting a double-star 336 light years away, has caught the interest of astronomers. The oddball behaviour of the planet, HD106906 b, provide clues about our own mysterious Planet Nine if it exists. HD106906 b and its behaviour have been described in a study

It may be offering clues to something that might be much closer to home: a hypothesized distant member of our solar system dubbed Planet Nine. This is the first time that astronomers have been able to measure the motion of a massive Jupiter-like planet that is orbiting very far away from its host stars and visible debris disk. NASA/M.
