    In our Solar System JUPITER is largest planet Jupiter has 1400 times the volume of Earth but only 318 times more mass. Thus, the mean density of Jupiter is about one-fourth that of Earth, indicating that the giant planet must consist of gas rather than the metals and rocks of which the Earth and other inner planets are composed.


     


    Outside: The planet, dubbed HAT-P-1, is located some 450 light-years from Earth in the constellation Lacerta. It is the largest planet ever discovered and boasts a radius nearly 1.4 times larger than Jupiter's.
