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.

Watching an exoplanet in motion around a distant star

A team of astronomers, using the Gemini Planet Imager (GPI) on the Gemini South telescope in Chile, has given us our best view yet of an exoplanet moving in its orbit around a distant star. A series of images captured between November 2013 and April 2015 shows the exoplanet β Pictoris b as it moves through 1½ years of its 22-year orbital period.
