New habitable zone super-Earth found in exosolar system
Washington DC (SPX) Nov 09, 2012
Astronomers have discovered a new super-Earth in the habitable zone, where liquid water and a stable atmosphere could reside, around the nearby star HD 40307. It is one of three new super-Earths found around the star that has three other low-mass planets orbiting it. HD 40307 is a dwarf star that is somewhat smaller and less luminous than the Sun that is about 42 light years away (12.88 parsecs). The previously discovered planets around it are called hot super-Earths because they orbit too close t ... read more
