The detection of these worlds has only been possible in the last decade, with the number of discoveries increasing enormously over the last year following the findings of the Kepler Space Telescope.There have been some truly stunning recent discoveries, not least the fact that there seem to be planetary systems around pretty much every star. Drilling down closer to learn more about individual planets we encounter "Mega-Earth," for example, Kepler-10c, which is made of rocks like our planet but is 17 times bigger, and orbits its sun in just 45 days; Kepler 16 orbits around a binary star system, while Kepler 11 has five stars, all closer in orbit
