Naked Scientist: Discovery of an earth-sized planet called Ross-128b

Chris Smith is popularly known to CapeTalk and 702 listeners as The Naked Scientist and joins the Eusebius McKaiser Show every Friday and does his best to answer questions either on science or just about anything under the sun from both 702 and CapeTalk listeners.

This week's science story: Discovery of an Earth-sized planet orbiting a cool, calm star about 11 light years away

Space scientists have confirmed the discovery of an Earth-sized planet orbiting a cool, calm star about 11 light years away.

As names go, Ross-128b belies the exciting potential of this remote, Earth-sized planet to harbour life. Perched in orbit around the dimly-glowing Class M red dwarf star called Ross 128, which is about one fifth of the size of the Sun, Ross 128b has taken researchers at the European Southern Observatory (ESO) more than a decade to detect.

The Naked Scientists says it has taken scientists; Xavier Bonfils and his colleagues about a decade to confirm the existence of this planet.

He goes on to say the planet has very good prospects of being Earth-like and possibly where life could be started.
