The existence of the elusive ‘Planet Nine’ in our solar system has been a hotly-debated matter in recent times.
Regardless of the continued hunt, astronomers haven’t been capable of catch a glimpse of Planet 9 since its existence was theorised.
However they’ve found an exoplanet 336 mild years away with the sort of eccentric orbit that might match with Planet 9’s personal route round our solar.
The large fuel exoplanet, HD 106906 b, travels previous the very fringe of its binary star system’s circumstellar disc in an orbit that takes 15,000 years to finish. It’s as if Jupiter travelled out previous the Kuiper Belt in our personal photo voltaic system.
If Planet 9 does exist, it might have an orbit considerably comparable – which might make it extremely troublesome to detect given all we learn about how the observable planets in our photo voltaic system transfer across the solar.
Though HD 106906 b was found in 2013, it’s taken till now for measurements from the Hubble Area Telescope to precisely calculate its orbit sample.

It’s not but clear how HD 106906 b achieved this unusual orbit. However one principle is that it shaped near its father or mother stars even because it was being dragged outward by the fuel disc. On the level it was shot outward from the 2 stars, a 3rd passing star stabilised its orbit and prevented it drifting by area as a rogue planet.
‘This method attracts a doubtlessly distinctive comparability with our photo voltaic system,’ defined Meiji Nguyen of the College of California, Berkeley, the lead creator on the research outlining the trail of HD 106906 b.
‘It’s very extensively separated from its host stars on an eccentric and extremely misaligned orbit, identical to the prediction for Planet 9.’

‘This begs the query of how these planets shaped and advanced to finish up of their present configuration.’
The system the place this fuel big resides is simply 15 million years outdated. This means that our Planet 9 — if it does exist — might have shaped very early on within the evolution of our 4.6-billion-year-old photo voltaic system.
