Does our earth have friends far away from the solar system? Whether the mystery of other planet creatures becomes true? A group of enthusiastic scientists are giving us positive sense to our curiosity!
An extrasolar planet, or exoplanet, is a planet beyond our Solar System, orbiting a star other than our Sun. As of 17 September 2009[update], 374 exoplanets are listed in the Extrasolar Planets Encyclopaedia. Extrasolar planets became a subject of scientific investigation in the mid-19th century.
On 16th September, 2009, a group of European astronomers said that they had found the first known rocky planet outside the solar system. The find by European Southern Observatory scientists in Garching, Germany, is an important step forward in answering the question of whether humans are alone in the universe, because it is the first of the more than 300 known exoplanets - as planets outside the solar system are known - that is not large and gaseous. CoRoT-7b has a density similar to Earth. Though the small exoplanet, CoRoT-7b, resembles Earth in many ways, it is far too hot to support life, This planet is about 500 light years from Earth!
