Detailed explanation-1: -The densest planet in the Solar System is Earth, which has an average density of 5, 513 km/m³ (344 lb/cu ft). The next most dense planet in Mercury, at 5, 240 kg/m³ (327 lb/cu ft).

Detailed explanation-2: -Earth is closer to that limit than anything else in our Solar System, and the combination of its relatively dense composition and its enormous self-gravity, as we’re 18 times as massive as Mercury, places us alone as the densest object in our Solar System.

Detailed explanation-3: -Mercury is the second densest planet of our solar system, second only to Earth. Mercury, surprisingly, also has a global magnetic field, which exists due to an even stranger phenomenon called antifreeze. Mercury is small enough to be a moon. Jupiter’s moon Ganymede and Saturn’s moon Titan are both bigger than Mercury.

Detailed explanation-4: -Density of Jupiter: composed largely of gaseous and liquid matter) Jupiter has a lower mean density than any of the terrestrial planets. However, at 1.326 g/cm3, it is also the second-most dense of the gas giants.
