HD 40307g illustration (Univ. of Hertfordshire) Astronomers announced Wednesday the discovery of a "super-Earth" extrasolar planet within the habitable zone of a nearby star. Astronomers said the planet, one of six known to orbit the star HD 40307, has a mass at least seven times that of the Earth and orbits the star at a distance similar to the Earth's distance from the Sun. HD 40307 is a K-class star about 42 light-years from the Sun; astronomers found three exoplanets around it in 208, but updated techniques that improved the sensitivity of radial velocity observations allowed astronomers to detect three more, including the super-Earth.
