We report the detection of a hot Jupiter-type exoplanet, named CoRoT-17b, detected by the CoRoT satellite. It has a mass of 2.43 ± 0.30MJup and a radius of 1.02 ± 0.07RJup, while its mean density is 2.82 ± 0.38 g/cm3. The orbital period is 3.768125 ± 0.000257 days and the orbit is circular. It orbits an old (10.7 ± 1.0 Gyrs) main-sequence star making it an intriguing object for planetary evolution studies. Its internal structure is not well constrained yet and it can be a pure H/He giant as well as it can contain ~320 earth masses of heavier elements.
