[6296] Planetary Sciences: Solar System Objects / Extra-Solar Planets

Scientific paper

Since the earliest times, through the Greeks, to Galileo and Hubble, astronomy is the science which positions humanity in the Universe. One of the most significant goals of contemporary astronomy is the detection and characterization of planets similar to Earth. A significant step towards this major breakthrough has been recently achieved with the discovery of several extrasolar planets with masses less than 10 Earth masses. Indeed, since 2005, the year of discovery of the first object belonging to this so-called 'super-Earth' category, two dozen of such objects have been detected. This rate will certainly increase, as planetary formation models predict a high frequency of super-earths in planetary systems. However, their low masses and small radii make their characterization challenging for current ground and space-based facilities. I will present a census of the current known super-Earth population and show what we can learn from observational constraints provided by photometry and radial velocities techniques. I'll then discuss the prospects of finding the first rocky exoplanet orbiting in the habitable zone of its host star, the next logical step towards the detection of an Earth's twin elsewhere in the Universe.
