Super-Earth has rocky surface: study
The smallest planet yet detected outside our Solar System appears to
have a solid surface, European astronomers say.
In a paper to be published in the journal Astronomy and Astrophysics, the
European team describe the exoplanet CoRoT-7b, a so-called Super-Earth,
which has a diameter approximately twice that of Earth.
The astronomers say the planet orbits its star once every 20 hours, making
it the shortest orbital period yet detected.
