The exoplanet Corot-7b has a mass five times that of Earth's and is the closest known exoplanet to its host star. The probable temperature on its "day-face" is above 2,000 degrees, but minus 200 degrees on its night face. This artist's impression of the planet comes from the European Southern Observatory and shows how it may look like if it were covered by lava. L. Calcada/ESO hide caption
