CoRoT-2b (formerly known as CoRoT-Exo-2b[4]) is the second extrasolar planet to be detected by the French-led CoRoT mission, and orbits the star CoRoT-2 at a distance of 700 light years from Earth towards the constellation Aquila. Its discovery was announced on 20 December 2007.[5] After its discovery via the transit method, its mass was confirmed via the radial velocity method.
