Exoplanets or extrasolar planets, are planets that orbit a star other than Sun. A few hundred exoplanets have been detected till now around nearby stars. With more sophisticated telescopes and techniques, scientists expect to find a large number of exoplanets in the near future. It is estimated that at least 10% of sun-like stars have planets, and some of them may have conditions that can support life, although most likely significantly different from life as we know on Earth.
