Hubble pins down weird exoplanet with far-flung orbit
A planet in an unlikely orbit around a double star 336 light-years away may offer a clue to a mystery much closer to home: a hypothesized, distant body in our solar system dubbed 'Planet Nine.' (2020-12-10)

Exoplanet around distant star resembles reputed 'Planet Nine' in our solar system
Astronomers think planets can exist in orbits far from their star, and propose a two-step process: interactions with the star or inner planets kick it out of the inner system, and then a passing star stabilizes the orbit to keep it bound. Such a scenario could explain the hypothesized ''Planet Nine'' in our solar system. Astronomers has now confirmed that one binary star system, HD 106906, has a planet in a bound, highly eccentric orbit. (2020-12-10)
