Artist's impression of the Gliese 667C system
New observations of the star, known as Gliese 667C, were combined with existing data to reveal a system with at least six planets. Three of these planets were confirmed to be super-Earths — planets more massive than Earth, but less massive than planets like Uranus or Neptune.
And even more exciting, these three super-Earths were found to be within their star’s habitable zone - a thin shell around a star in which water may be present in liquid form if conditions are right and making them possible candidates to support life.
This was the first time that three such planets had been spotted orbiting in this zone in the same star system!
As Mikko said: “Finding three low-mass planets in the star’s habitable zone is very exciting!”
And so does the APS!!
