NSF/Zina Deretsky – The orbits of planets in the Gliese 581 system are compared to those of our own solar system. The Gliese 581 star has about 30% the mass of our sun, and the outermost planet is closer to its star than we are to the sun. The fourth planet, G, is a planet that could sustain life. more> http://tinyurl.com/3x8h4ej
