The exoplanet CoRoT-7b is the seventh planet detected via transit photometry (Fig. 1) by the European space telescope, CoRoT (Léger et al. 2009). With a radius of ~1.6 Earth radii, this planet is the first potentially terrestrial-like planet found outside our solar system. CoRoT-7b revolves around its central star in a very short-period orbit of 20 h making this planet one of the few with extremely small orbital periods. The close proximity of this planet to its Sun-like host star (which is about 500 light-years away) implies that it must experience extreme conditions. For instance, its surface may be covered by lava or boiling oceans (Fig. 2).
