Scientists discover three 'super-Earths'
A nearby solar system is packed with up to seven planets including three "super-Earths" that may be capable of supporting life, scientists say.
The planets orbit Gliese 667C, one of three stars bound together in a triple system 22 light years away in the constellation of Scorpius.
Astronomers believe they fill up the star's "habitable zone" – the orbital region just the right distance away to permit mild temperatures and liquid water.
Three of the new worlds are categorised as "super-Earths", meaning they have between one and 10 times the mass of the Earth.
