Exiled exoplanet kicked out of star’s local neighbourhood?

A planet discovered last year sitting at an unusually large distance from its star — 16 times farther than Pluto is from the Sun — may have been kicked out of its birthplace close to the star in a process similar to what may have happened early in our own solar system’s history. The planet’s 13-million-year-old parent star is known as HD 106906 and lies 300 light-years away.
