Abstract: Nearly 120 Jupiter-mass extra solar planets have been discovered. The determination of their properties provide valuable supplements to the solar-system dynamical and meteoritic data and stimulate rapid progress in the theory of planet formation. Recent investigations indicate that 1) through a self regulated process, the amount of heavy elements retained as planet building blocks is comparable to that empirically inferred for a minimum mass nebula, 2) the critical stages of planet formation, from grain condensation, planetesimal coagulation, to gas accretion, proceed through local heavy elemental enhancement on the time scale of a few Myr, 3) the masses and period distribution of planetary systems are distinctively divided into rocky planets, gas and ice giants, by their formation environment, and 4) the detection probability of gas giant planets is greatly enhanced in metal-rich protostellar disks.
