Description
Super-Earth extrasolar planets. Computer artwork of a trio of super-Earths discovered using the HARPS spectrograph on the European Southern Observatory's (ESO) telescope at La Silla, Chile. A super-Earth is an extrasolar planet with a mass higher than the Earth's, but substantially below the mass of the Solar System's gas giants. The term does not imply anything about the surface conditions or habitability. These planets have 4.2, 6.7, and 9.4 times the mass of the Earth and orbit the star HD 40307 with periods of 4.3, 9.6, and 20.4 days, respectively.
