CoRoT-16b is a transitingexoplanet orbiting the G or K typemain sequence starCoRoT-16 2,433light years[4] away in the southernconstellationScutum. The planet was discovered in June 2011 by the French-led CoRoT mission. CoRoT-16b was detected using the transit method, which measures the brightness changes during an eclipse. However, this planet has an eccentric orbit, which is unusual due to CoRoT-16b's proximity to its parent star and the age.[1]
Due to its orbit, CoRoT-16b is classified as a "hot Jupiter". It only takes about 5 days to orbit CoRoT-16, but has an unusually eccentric orbit. CoRoT-16b has 52.9% the mass ofJupiter, but is 17% larger than the latter. Due to the low mass and high radius, CoRoT-16b has 41% the density of water; the orbit gives it anequilibrium temperature of 1,086K. However, this is only an estimate due to the eccentricity of CoRoT-16b.
